X-Callback-URLs to other apps on mobile

I would like to be able to open X-Callback-URLs to other apps on mobile like I can do it on Mac, e.g. x-devonthink-item:// Other note apps on iPhone/iPad can do that, but in Capacities mobile I just get a message "Only supported in the Desktop App". This is annoying as I have to duplicate documents/pdfs and save the additional one in Capacities.
