Make a left panel not auto collapsible in MS Teams

Question

After I pressed some keys on keyboard this panel has disappeared and now appears only on mouse hovering:

How do I lock it back again?

UPD. Below are some screenshots.

Answer 1

I was able to replicate your issue. When I changed the zoom level to 145% like you did & moved Teams to another monitor with smaller resolution (1024x768px) it hide this left bar. Teams is trying to give you more area for things with the limited room it has. This is normal & I don't think there is anyway to fix. Ideas:

1. Increase the resolution of your monitor
2. Turn down the zoom level in Teams
3. Adjust (DPI?) text size within Settings, System, Display, tweak top bar:

Answer 2

The zoom did it for me. I was at 105% and got the "pinning" back when I lowered it back down to 100%. Had no idea why this started happening. This makes perfect sense. Thank you for the suggestion.
