Conversation
Surfaces the new per-user Slack notification settings for the signals
inbox (workspace + channel + minimum priority) in the inbox source
settings panel. Reuses the existing /api/.../integrations/{id}/channels/
endpoint to populate the channel picker and the existing slack
Integration store, so no new auth setup is required — users connect
Slack once in PostHog Web and pick a channel here.
Pairs with the backend changes in PostHog/posthog#58774.

Adds an in-app Slack connect flow so users no longer have to leave PostHog Code for the PostHog web settings page just to wire up notifications. Flow: clicking "Connect Slack workspace" in the inbox source settings opens the browser to PostHog Cloud's Slack OAuth authorize endpoint with `next=/account-connected/slack-integration?...`. PostHog Cloud completes OAuth, creates the team-level Slack `Integration`, and redirects to a landing page that fires a `posthog-code://slack-integration?...` deep link back into the app. The new `SlackIntegrationService` (main process) handles the deep link, emits a callback event, and the renderer hook refreshes the integrations list. Mirrors the existing `GitHubIntegrationService` so each provider's deep link handler stays isolated. Pairs with backend changes in PostHog/posthog#58774 that teach the `/account-connected/<kind>` page about the new `slack-integration` kind.

… channels Switches the notification channel picker from a Radix Themes Select to the searchable, virtualized Combobox from @posthog/quill (the same component used by GitHubRepoPicker and BranchSelector). Workspaces commonly have hundreds of channels — the old Select was unsearchable and rendered every option upfront. Also rewires handleUpdateSlackNotifications to apply changes via setQueryData optimistically, rather than waiting for the round-trip + cache invalidation. On error, rolls back to the previous snapshot. This makes channel and minimum-priority picks reflect immediately, and surfaces failures via toast.

Extract shared debounce logic and adopt it in IssuePicker.
…ings Debounce combobox input and query the integrations channels API so large workspaces are searchable. Add modal-safe Quill portal handling for the inbox configuration dialog and shared settings dropdown styling.
Replace em dashes with en dashes in inbox strings for typography consistency.

Problem
Signals inbox items previously surfaced only in-app. Users wanting a heads-up when a new item lands and they're a suggested reviewer had no way to opt in.
Even after the initial Slack notifications work landed, picking a channel still required a detour through PostHog Web — users had to leave PostHog Code to install the Slack integration, then come back. That's too much friction for what should be a one-time setup.
Changes
Adding Slack notifications under Inbox source settings.
What it includes:
Integrationis connected; otherwise the single workspace is implied)./api/environments/{teamId}/integrations/{id}/channels/- same endpoint as Insight Alerts. Includes an explicit "Off" option.Also, in-app Slack connect flow so users no longer have to leave PostHog Code for PostHog Web.
SlackIntegrationServicein the main process. Mirrors the existingGitHubIntegrationServicebut registers a separateslack-integrationdeep-link key so each provider's handler stays isolated.slackIntegrationtRPC router.SignalSlackNotificationsSettingsshows a "Connect Slack workspace" button that runs connection without redirecting to the Integrations page of Cloud settings.Pairs with the backend changes in PostHog/posthog#58774.
