as in the title, I see items related to an iteam, with their IDs, and with possibility to copy the ID, or to see it with bigger chars. I think this is quite useless (view, copy and big char representation) so it might be not an intended behaviour.
Something like to open the releated item could have a sense, like it happens in desktop apps, and mobile ones.
1Password X beta 1.21.1 (build #20117). Same behaviour from Chrome (84.0.4147.89) and Firefox (78.0.2). Both are the last stable release.
In the picture you can see the Item 2 view, with Item 1 paired to.
