I just discovered that that all #CNRS members (so basically everyone in a CNRS lab) have access to a version of the online #LaTeX editor #Overleaf with no restriction on the number of collaborators on a project and on the compilation timeout. https://plmlatex.math.cnrs.fr/project I haven't tried it yet but it seems pretty handy (it's based on the open source version of Overleaf so the interface looks very similar).

Bonne nouvelle, merci !
