like "more info"(linking to inApp Help), "Deny", "Allow" and a checkbox "remember choice for this webxdc app"

would mean you need to track per-app what is allowed, and then allow folks to change it later -- quite some UI and user-communication effort.

whatsapp and signal enable P2P by default for voice-calls and have a single global option "always relay calls"/"Protect IP address in calls" which defaults to "off" for both, and is in advanced options. Probably makes sense as a global option because either you care or you don't.

ASFAIK iroh/integration is not able to do User1->relay1->relay2->User2 yet so if i am not mistaken we can not right now offer it like this. I tentatively suggest to only introduce a global option to enable/disable ephemeral channels and have translated strings for what it means, and probably default to off at first.

I also think that a single configuration option should suffice. Maybe we can talk to the iroh people about our need for IP address protection.

So we decided to squash merge this when the time is ready.

• This depends on a core with this pr merged https://github.com/deltachat/deltachat-core-rust/pull/5607, so as of the time of writing this it is not merged yet.
