Currently we have Teams defaulted to show you the first (up to five) channels ever created. If you want to add more channels to your left rail view, just click the ellipses next to the channel name and select “Favorite”. When you favorite the channel, it will then be “pinned” to your left rail under that team name.
Try that and let me know if that meets your needs!

I have a similar question to Belinda's below (I didn't see a response...). I would like to be able to plan content in different channels ahead of time but not show the channel to the class right away. Is there a way to hide channels from students in your class (not just label them as "hidden")?
