UR22 C reverb not applied on Instagram Live

I just got my UR 22C and connected it to my iPhone 13 pro max. The intention of getting the UR22C was to use it for Instagram Live for singing using the dspfx Reverb. But when I go live the FX does not apply to the live stream just my dry voice. How do I use the reverb from the dspfx for Instagram live ?

The loop-back setting must be set to either “Live Stream” or “Voice Chat” for 'verb to be passed back (make sure your firmware is the latest).

thanks a lot
