Aukey EP-T28 - microphone doesn't work on Whatsapp

Hi there, I paired my brand new Aukey EP-T28 with a Samsung Galaxy S20+ and then with a Huwei Mediapad. In both cases I can’t find a way to use the microphones on the EP-T28 for whatsapp vocal notes. I can hear the vocal notes from the earbuds but when I make one, it uses the phone’s/tablet’s microphone. I cant’ seem to find any option to correct this. What can I do? Thanks
