Trying to use a lapel mic with my Android phone to no avail.

Hey, I just bought a Hollyland Lapel mic on Amazon hoping I could just plug it in to my Google Pixel 3a (via audio jack), but I'm struggling to figure it out. I've tried several audio recording apps and none of them seem to give me the option to record with an external mic that isn't bluetooth.

Am I just missing something, or have I simply made a bad purchase and should buy a mic pack instead?
