No Audio for Soundcore Sleep A10 earbuds

[EMo-]

I have some sleep earbuds, the Soundcore Sleep A10 earbuds which have excellent battery life.  I was hoping to use them for Zoom calls.  They are audio only and come without a microphone.  All other Mac apps work with them just fine, but that is not the case for Zoom.  Best guess is that Zoom is using the bluetooth profile for headsets instead of speakers, since the listing for my Soundcore Sleep A10 earbuds shows up in the listing for Microphone choices as well as Speaker options.  Unfortunately, no sound will route to them no matter what I do.

  Any way to convince Zoom that they should use a speaker-based bluetooth profile/protocol for these instead of the headset profile/protocol?    (I use the laptop's built in microphone or a lapel microphone for the voice piece)
