Macrodroid: how to check the level of brightness with "if-clause" (conditions/loops)

I would like to increase the brightness of the device from 0 percent to 100 percent if some trigger occurs (e.g. at volume button's long press). I have created a macro as follows but it does not work: when I press volume button's long press the brightness does not change from 0 to 100. More information: - I am able to set the brightness to 100% outside of "if-clause" in Macrodroid. - "Volume Down -Long press" works without problem as a trigger with other macros (if any). - I have tested with or without option, "Alternative Android 9+ mode". - The android version of the device is 12. - I also tested with the option "Brightness Less than 1%" in "if-clause" without success.
