French horn microphone

Hello everyone!
I have recently started with online classes and I would like to know what microphone other horn teachers, or other brass teachers, use for their classes.
I am undecided about using the internal microphone of the computer (which offers a medium-low quality, but allows to speak and play with the same microphone) or to use a specific microphone for the horn. I currently have a Shure SM57 (it offers good quality), but this prevents me from using the computer at the same time to speak.
Would someone help me to indicate which is the best option? What microphones do you use?
Thank you very much for your help.
Regards.
