Serial passthrough to Holybro H-RTK F9P rover lite

I’ve been trying to connect to a Holybri H-RTK F9P Rover Lite GPS connected to GPS1 on a cube orange using serial passthrough.

I followed the guide in the wiki, set baud rate for serial 3 to 230 and function to -1, set serial timeout to 45 and serial_pass2 to 3. However, u-center isn’t able to connect even when manually setting baud rate.

Anyone have this module? Any suggestions?
Any help would be appreciated!
