Add the persistent anxiety that you are missing something you should not have and you end up with constantly refreshing the feed instead of working - just like social media and exact opposite of what you want.

MS Teams cause enough headache by sorting the messages by "latest updated thread" completely obliterating the mental model of the conversations in the channel I have.

Some ideas for ideal team chat:

* Automatically build threads or tag messages by topic in threads so you can easily filter out the topics interesting to you - often there are multiple discussions intertwined that should have been in separate threads but people just reuse the threads

* Collapse the resolved discussions into a conclusion (with option to view the discussion) - when the discussion goes into shootout of messages you might be interested only in the conclusion, not how they got there

* Announcements - sometimes you really just want to announce something (on company wide scale, team scale, or just personal Tweet sort of thing) - make these separate and browsable - here the automatic feed construction sounds appropriate

* Activity digest - at last workplace I liked the Confluence digest email as it brought attention to projects and topics I was not directly involved with - nothing happened if I missed those, but was nice to keep an eye on some of the initiatives

It is super important to make a tool the people can trust - no one likes to make or hear excuses like "sorry I did not see the message".

We definitely need better tools for communication, so keeping fingers crossed for your success.
