Keyboard shortcut for "Copy mailbox permalink" feature

Hi! Is there any way to map shortcut to the feature ("Copy mailbox permalink), so I can process my inbox without using trackpad - keyboard only?
Thank you for your help!

I use mailspring only for my mailing routine. I have chosen it recently as only fine, os and free mail client available for macos - and mostly because of the permalink feature.
I follow zero inbox approach, which is, as far as I get, about cleaning email for one run, storing long term tasks to task tracker.
So I get permalink for email containing some task to do and attach it to my task tracker, so I can come back later without wasting time on search.
But it seems the feature is only has no keyboard shortcut, so I do all actions with keyboard and have to use trackpad for the opening context menu and pressing it’s button.
