Can the agent doing the Remote Assist Session end the session or did I have to end it manually myself?

I was in a Remote Assist session because of an issue with my computer but at the end of the session the session just close automatically and the Dell remote Assist app was no longer in my device.

I just wanted to make sure if this was because the Agent ended it themselves, or  was I supposed to be the one to press the button for ending the session?
