Slack workspace not found error when using pagerduty_slack_connection

We face an issue when creating a pagerduty_slack_connection. It appears that the provider cannot connect to the workspace. We followed the steps in the documentation to authorize the workspace as Pagerduty integration in the GUI. Then we fetched the Slack workspace ID (starting with a T) using this guide.

│ Error: POST API call to https://app.pagerduty.com/integration-slack/workspaces/TXXXXXXX/connections failed 404 Not Found. Code: 0, Errors: <nil>, Message: The PagerDuty has not been connected to this workspace. Please complete the installation and try again.

Anyone has a clue on why it cannot find the workspace? Or might this be a bug in the provider?
