iPad Pro 11″ – Bug magic keyboard pendant appels zoom/messenger

Hello,
I bought a magic keyboard (white in bluetooth) for my note taking on ipad pro 2020.
My problem is that when I take a zoom course or a messenger call I can no longer write with my keyboard on Pages or other third-party applications like Good notes … as soon as the call ends I can write again with.

This bothers me a bit because the interest of the keyboard was the note taking in progress …
This problem occurs with airpods pro connected but also without. Is there something to do?

Have a good day,
AT
