Tchap (the chat part of the suite) is indeed a fork of Element. Unfortunately they haven't funded upstream development for many years (otherwise both Element and Tchap would be much much better!)
Visio (aka meet) began in parallel with Element's work on MatrixRTC and Element Call. Hopefully the two can converge, given they are both built on LiveKit.

It really has been a huge disappointment the extent to which governments using open source projects for mission critical work go out of their way to avoid financially supporting them.
How much better could open source alternatives to Teams be in this moment if only 1% of what Europe paid Microsoft for Teams went to investing in open alternatives?
It boggles the mind as to why they choose a name for this application that is very clearly a Microsoft trademark.
In understand it's also the French word for Videoconferencing, but even still...
Oh I thought you said that you were doing custom features for the French government in a comment a few months ago. I must have misunderstood, sorry.
