Help Me Setup a Soundboard on MacOS 10.15 (Catalina)

So, I use a Macbook Pro 16” (2019) at work running Catalina (10.15), and I want to get a soundboard and re-route it back in so I can have it available in meetings (mainly Slack and BlueJeans). Any idea what my options are? So far I’m seeing mainly expensive stuff, like Loopback ($99) and Farrago ($49)

Any idea if there are cheaper options? I have an Audio-Technia AT2020 mic + Scarlett USB Setup for phantom power.

I really just want sounds for meetings, etc. Oh, and I don’t want to drop $500 on a GO-XLR. I don’t even think those are Mac-compatible.
