Hey, do you think it'd make sense for you to return true/false depending on whether you accepted (consumed/reacted to) the event? We could fall back to other consumers then.

Return a bool value in HandleMediaKey to indicate if the event will be handled by the approver.

Yes, good idea. Just changed the code to match your suggestion.

Did you perform an exploratory manual test run of the code change and any related functionality on device or emulator?
Yes

Did CI run pass? If not, please explain why.
No, but that's because the tests are being run twice, and in the second run it failed.

Have you checked that submitter has accurately filled out the submitter checklist and has taken no shortcut?
Yes

Code looks good and works as expected!

Hmm... this seems to crash unity8 when I call:

callManager.handleMediaKey(false)

use mApproverInterface instead of mHandlerInterface

Tried the current build from silo 19 (should be rev 997) but it still crashes with this backtrace:
