[MM3-users] Single-Sign-out for List member

Hello, I have to configure mailman 3 for a german company. The privacy policy in our country demands for mailing-lists, that its member can sign out in one step, it is called sigle-sign-out.

So I would like to ad a link in the footer of every message, with which every receiver/member can sign out of the newsletter with one click. It does not seam to be possible, to put this into effect with mailman 3. Does anybody have any hints, how to create a link, and when this link is called, the user is signed out of the newsletter. Thank you, Wolfgang
