I have worked with several companies and collaborating across vastly different time zones...and the thing that seems to work best is some central document repo/wiki. Sure, group chats help, 1:1 chats help, email helps...but for institutional knowledge, or even info that needs to be passed across time zones, i find it helps to "dump" info in a central place that everyone knows to look at like a doc repo/wiki...and a chat becomes too ephemeral, plus as new messages get added very critical info gets pushed down...and if a chat platform allows to "pin" some critical info, then you just pivoted to need a doc repo/wiki of some sort.
I will also add that if the info to be conveyed is less than institutional knowledge, and it more about "what's status of a project?", that too, can best be posted in some sort of succicnt dashboard...which can live somewhere in an appropriate place in your doc repo/wiki. Again, i will state again that ephemeral platforms like chat have their place, but there's nothing more powerful to ensure EVERYONE everywhere in your org knows what's up, what's happeneing, and/or how to get help to keep moving forward on all efforts.
