Blue jeti nano, Android Xiaomi, Jitsi

Hello,

I have a question as I can´t solve this: I have a Blue Yeti Nano Microfon which I want to use with my Android phone from Xiaomi to use Jitsi. But I don´t know how to select it as Microphone that should be used. I gave permissions in the configuration to the App to connect to “Microphone” but there i nowhere to select. When I use Jitsi Desktop I can select especifically the Blue Yeti Nano. But no idea how to do that with the phone. The microphone otherwise works perfectly, it works when I record something for example, so it is connected to the phone.
Could anybody help me with that?
