Additional team and channel-related features and issues within Microsoft Teams for business
Hi Luke
I'm AnnaThomas and I'd happily help you with your question. In this Forum, we are Microsoft consumers just like yourself no one here is a Microsoft employee.
Unfortunately, there isn't a built-in feature for chat within Teams channels. So, if you want to chat with your team members without leaving the Teams section, you can use the Posts tab in a channel. However, if you want to chat with a few people privately, or if you don’t want to clutter the channel with messages that are not relevant to everyone, you can use the Chat tab and create a group chat with the people you want.

I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.
Best Regards,
AnnaThomas
