Any e2ee app for group chat with a web interface?

Hi,

Trying to move group chat from telegram to a more private option, but the key feature is its web interface which is so convenient...

I've checked SimpleX, Session, Briar & Element-Matrix, but the first 3 do not have a web version and the latest only has a free version for self-hosting and I haven't looked into self-hosting yet.

I'd completely understand if what I'm looking for doesn't exist for free, but if anyone has a suggestion here, I'm interested!

Cheers
