Missing networks?

[Another-Joe]

I'm feeling like a bit of a dunce, but simply cannot find answers to this.

Neither Wax nor Telos are showing up in my networks list. I've accessed Telos before, but maybe with another wallet. I've never accessed Wax, but I had an account automatically created because I have some BET tokens. But I can't even turn it on since it's not showing up. None of the tutorials I'm finding address this specifically. They just tell me to toggle the network and go from there.

What am I missing?

Also, is BEOS supposed to be showing up? I don't see it either.
