Summary of Changes

Hello @chulspro, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant enhancement to the camera's two-way talk verification popup by adding microphone mute/unmute capabilities. This feature provides users with greater control over their audio input during validation sessions, improving the overall user experience and interaction with the system. The changes involve UI updates, state management, and integration with the underlying WebRTC service to manage audio tracks.

Highlights

• Microphone Mute Functionality: Implemented the ability to mute and unmute the microphone within the two-way talk verification popup, giving users more control over their audio during validation.
• User Interface Integration: A clickable microphone icon has been added to the popup modal. This icon visually changes to indicate whether the microphone is currently muted or unmuted, enhancing user feedback.
• WebRTC Stream Control: The mute functionality is integrated with the WebRTC service, allowing direct control over the local audio stream by enabling or disabling its tracks based on the mute state.

Code Review

This pull request adds a mute/unmute functionality for the microphone in the two-way talk verification popup. The implementation is mostly solid, introducing a new UI element to control the microphone and the corresponding logic to toggle the audio track's enabled state. However, I've identified a logic issue that could cause the UI's mute status to become out of sync with the actual microphone state. I've also provided a suggestion to simplify the CSS for better clarity. With these adjustments, this will be a great feature.
