Open instances in South America?

Via the site https://github.com/jitsi/jitsi-meet/wiki/Jitsi-Meet-Instances I could find some publicly available instances which, with some restriction, can be used for our needs.

Unfortunately I didn’t find any instance in Brazil and most of the listed ones in South America aren’t up to date, don’t give admin rights or don’t work.

Does somebody have an updated list for this region?

Thanks in advance!
