    Hello, I found TypeError in the library: Cannot read properties of undefined (reading 'validateOutgoingMediaTracks')

    Here are the steps to reproduce it:

    My browser (Google Chrome) is closed , now I'm opening it for the first time - it's important !

    1. Open https://sdk-cdn.mypurecloud.com/webrtc-sdk/demo/webpack/
    2. Write access token in ‘Use custom access token’ and click Use manual auth token
    3. Open Console
    4. Click Start App
    5. Find in Console error:

    The error is repeated in both version 6 and 7.

    Library Errors should be reported via customer care case to ensure they get properly tracked and resolved as expediently as possible.
