Toggle checkbox visible and not visible

hello Adalo fan, I am one too.
In my development for my application, I am block.
I am creating an application to book a nanny if you need them.

the issue is that i reach the place were the user can add or remove booking_work_time.
when he do so, I would like to make visible empty checkbox invisble when work_time is choose and visble if the worktime is deselected.

please do you have an example of your development that do so.
How i could handle it.
thank you I hope it is clear.
