MicrosoftStsOAuth2Strategy - Failure Result Android 28

[Petri-X]

Hi,
I have played with AudioCode's IP phone for Microsoft Teams and when doing a provisioning for the device I can see that the phone writes into log the following lines:
10:08:45.251 10.92.16.166 local6.warn W/MicrosoftStsOAuth2Strategy:TokenResult( 1964): [2022-09-29 07:08:45 - thread_name : pool-22-thread-3, correlation_id : 8a3920b9-905e-440b-8cda-1b0e30faf586] Failure Result Android 28
10:08:45.253 10.92.16.166 local6.warn W/MicrosoftStsOAuth2Strategy:TokenResult( 1964): [2022-09-29 07:08:45 - thread_name : pool-22-thread-3, correlation_id : 8a3920b9-905e-440b-8cda-1b0e30faf586] Error: authorization_pending Android 28

Any clue what that error might means?

This is happening when I'm trying to do a remote sign-in to the device using Teams Admin Center.
