Activate windows with title not working

Hi,

I am trying to do keybaord shortcut that maps F1 to 'Activate windows'.

I want to activate a window that contains the phrase 'mobileapp' in its title. I have tried many different windows.

I have tried different combinations to no avail (regex).

It just does not work at all.

mac Tahoe 26.5

BTT 6.526

The window im trying to activate is in the same space/desktop as BTT that is currently activated.
