App target api 30 error google play

I get this error while i upload my application
Your app currently targets API level 30 and must target at least API level 31 to ensure it is built on the latest APIs optimized for security and performance. Change your app's target API level to at least 31.
What can I do

Wait until AI2 targets API31, which should be in a few days.

If you just cannot wait, you can edit the mainfest:

Target API level 31

Thank you for your assistance
