Finding the microphone settings on Android One 10

My headset microphone has stopped working recently, and I would like to have a look in the microphone settings to fix the issue. However, I cannot find any setting related to the microphone volume, noise filters, etc. (such as described in point 1 here ) in the settings app. Where could I find the related settings? I cannot imagine that there are no microphone settings, but if this is the case, could there be an app that would give me more control? I am using Android One 10 on a Nokia 6.2.
