Hey @fcjr-ghostery, thanks for your post.
You can find further information about our process for auto connections here. Please note that for some interfaces, there is no need to request approval, meanwhile for others you need to add a justification here detailing why you are requesting them.

Note that a snap declaration is needed for your snap to be delivered via the snap store and claim this well-known DBus name (simply upload the snap to the store and request a manual review and a reviewer will take a look).

Let us know if you have further questions.
Thanks!
