I am using Page Layout Builder
I have 2 Frames.

Frame1 has a TabControl, with 3 panes.
Each Pane has a GridComponent.

Frame2 has a gridcomponent.

The Page Layout Part Properties has an option for setting a link, but it seems... incomplete. I'm never asked what to link the grid to, and therefore, when I try to map out the linking fields, it is... unsatisfying as nothing is there.

What's up?
