How to display ACF relationship subfield?

I’m wondering wether anyone has managed to display an ACF relationship subfield (an ACF field that is embeded in either a repeater or flexible content field). I’m aware of the relationship option on the “show posts” action of the pinegrow wordpress plugin. Which works very well with a regular relationship field but doesn’t seem to work when it is a subfield. Has anyone discovered how to get that working (or has perhaps found some sort of workaround)?

I’ll leave a little bump here.
