Cmd+W to close window

Hi is there any way to make Cmd+W work with closing the window? I've tried Cmd+H as well, the only way to close the window (and leave it in the background running) is clicking on the red X button. 

I am running Sonoma 14.4.1 on a 14" M3 MBP

BTW, THANK YOU SO MUCH FOR THIS APP!
