An online classroom just released a new version. Some of the teachers there need to get familiar with the new system.
There is a button called "raise hand", which is in grey background color by default, as shown below.
When I click the button, it turns blue and keep blue until I click it again.
I am helping one of them with raising hand feature. I click "raising hand" button in my end and check if the teacher on the other end can see it.
Can you see I'm raising my hand?
Is the sentence clear, grammatically correct and polite?
