Ceiling light T1 and light switch H2 (2 channels, 4 buttons)

Hi guys,
I installed some time ago the ceiling light T2 and in my Aqara app I have two widgets which are duplicated. It’s really confusing. When I delete one the other one also get deleted.

Today I installed the H2 light switch and I have a problem with setting it up.
Ideally left switch (top) I would like to work to turn on the white light
The right button, I would like to be responsible for the RGB light.
The bottom one I have no idea but I was thinking that top ones will be turning on the light and bottom turning off the light.

Do you have an idea how I can use it or set it up?

Hi, bottom should be a virtual button for automations

Ok then, so how can I connect the top buttons to the bottom and side light? As in the app it appears under one widget. Unless I’m doing something wrong and it’s not a logic work
