Dear Sir,
Greetings! 
There is no option to hide the toolbar/taskbar at the bottom of the meeting window. If an option is provided to hide it, it will increase the precious space.
Warm regards,

Currently there is no such an option. I pass it to product team to consider.
Thank you,
Eugene
I hope, someone is working on this feature.
