Aeotec Pico Shutter (Zigbee) with ZHA - change attribute

I have the Pico Shutter form Aeotec successfully paired with ZHA.

Change Attribute: Switch Mode

I would like to know how I can change the switch type to Momentary switch. In the manual, it says that the 0xFD00 attribute needs to be changed to 0x01

In ZHA I cannot select any option in the dropdown field.

What is the right way to change an attribute?

It would also be good to see what attributes are set.

Thanks for your help!
