If you don’t want to install yet another application but want to use more simple thing, I have e-mail solution. You can shoot e-mail to firstname at fastmail dot com. You can always send me an “Hi” e-mail if you are new in my Pages. I love to talk people in random topics. Just a side note, if you are here to send advertisement, then I’ll suggest you to not do that.
I also can send you Jitsi link via e-mail if you want to use something similar to awful Zoom.
If you don’t want to use any of these methods, I am sorry for now.
