Super beginner setting up for podcast

Ive seen all the YouTube clips including the Adobe official about how to set up the podcast.

Equipment: Blue Yeti microphone, Google meets

macOS: Big Sur

latest Adobe Audition

I would like to invite the guest on my podcast from zoom or Google meets. However the host is input set as my microphone. but the input of the interviewers does not have the internal audio as a preset.

audio software from preference only allows you to select single option, hence I'm having trouble separating my channel and my interviewers channel.

i have blackhole, ladiocast installed but I am not sure how to connect these two into Adobe audition.

Anyone can help?
