How do you switch back to your leader?

[Scorcher24]

I switched from the commander of the team to the engineer in mission 2 to disarm the mines. After doing so I wanted to switch back to the team leader but I am unable to do so since all commanding controls are gone.

How do I switch back to the commander once I am done disarming mines?

edit: NVM found it out. Just had to press T. That button was not mapped for whatever reason.
