How to setup the brain, controllers, and have it work without controllers on the vex IQ chrome extension (our school gives us chromebooks)

For my engineering class, we are using the IQ and V5 robots (my group is IQ), I already figured out how to get the IQ extension and now I just need to find out how I could set up the brain and also how to use controllers and how to have the robot work/switch between the two. Any advice is helpful thankyou.

The tutorial videos and example programs included with VEXcode IQ are a great place to start.

The Knowledge Base and STEM Labs are also useful resources.
