USB mixer with ZOOM

[Buzzardluck]

I host a hybrid meeting once a month. I use a 1 XLR mic into a mixer. Then USB into a laptop running the remote meeting. I want to add a wireless mic for the audience to use because the remote people can't hear questions asked. My problem is getting the sound balanced for the remote people. They can barely hear anything from the speaker and if I unmute a remote person, they are extremely loud. I think I'm missing a setting, but don't know what it is. TIA
