Rearrange icons on taskbar?

I’m new to Manjaro Cinnamon and I’d like to rearrange the running app icons on the taskbar. I have tried but I can’t find the way. Could someone tell me how it’s done please?

Right click on an empty part of the panel and choose “panel settings” at the top.

Thank you. That allows moves for system icons like sound and wifi but the running app icons for Bitdefender, Mailspring and Torguard won’t move.

They should they do here, you just have to click in a blank space between two of the icons.
