Simulate the mouse movement instead of limited drag and click

• I have checked that a similar feature request does not already exist.

Is your feature request related to a problem? Please describe.
I tried to use Phone as my cloud gaming console.
I downloaded Geforce Now for Android, it is not available on Linux.
I successfully launched and used it with the Android phone.
I connected the Android phone and mirrored the screen.
I was amazed, however the limitation was I couldn't move the vision of my character in the game.
The case was scrcpy does not simulate mouse movements at all.

Describe the solution you'd like
I would like to see a working full featured mouse control, or at least smooth mouse movement while playing the games on my new gaming console that is my Android phone.

Describe alternatives you've considered
Sending mouse movement events would be still great. But a simulation of a mouse would be way better. It is known that you can connect a mouse to a Android device. I would like to have the same mouse experience with scrcpy as if I connect the mouse directly to Android device.

It's very similar. But I'm in doubt.
It's so bad GitHub doesn't have ability to group issues and make a map out of them. Now the only choice is to leave the issue opened and leave it disorganized among other random issues while linked to the main issue.
