Integration with Proton Calendar (auto. WIRE conference creation)

User Story

As a WIRE and Proton user
i want to add a WIRE conference call easily / automated to my Proton calendar event invitations
so that i don`t need to manually open WireApp to set up a conferencing call and copy the link manually to the calendar event.

Rationale
As a proton user i already value privacy and data security.

(1) Since a couple of month Proton offers an own encrypted conferencing tool. But its only web based and does not go beyond conferencing - messaging outside of a conference is not in scope. WIRE would close both gaps.

(2) At the same PROTON offers a whole ecosystem of privacy tools. That is a general problem for users. If you use multiple PROTON services at the same time (all eggs in one bag) you are done in case of a breach on provider level.

It would be great to reduce the accumulated risk as a proton user and move the conferencing part to WIRE.

Additional information
- Proton Calendar already has internal (proton meet) and external zoom integration that works fine.
Just add your service in collaboration with Proton to that list.
- The invitation e-mail should include the recipients as WIRE guests by default.
- There should be a function to add existing WIRE user account name ( @username ) to recipients
