Regarding the issue of window size when using Windows Remote Desktop

When I use FlowLauncher while in the Windows Remote Desktop, the width becomes extremely wide, making it impossible to move the mouse to the left or right edges to make adjustments, like this:

One solution is to press Alt + Win + Left, but I think there should be a better way to solve this problem.
By the way, the remote computer monitor is 4K, but when using it remotely, it is set to 2K.
