More detailed chat invite link preview

Feature Proposal
1

Hi all, I’m wondering if it’s possible to develop link previews for link-based invites to dc itself ? Currently, sharing a link inviting a prospective dc user to chat with you is intimidating to most (massive cryptic url), so would benefit from some kind of embedded preview that displays Message XYZ on Delta Chat or Join the XYZ group chat

EDIT, I realize there is a neutral Message privately on Delta Chat preview, so my inquiry is more about including some of the existing slug info in this preview, e.g. if it’s a group chat, it could be a more opinionated message like Join the XYZ group chat. In theory, this is actually more transparent, signaling to the potential user what they’re getting themselves into before committing.

For individual chats and group chats, the sharer’s username is already in the share link. For group chats, the group name is also in the share link. So it could be something like:

  1. Message XYZ on Delta Chat
  2. Join XYZ in 123 on Delta Chat

I don’t think it is possible. https://i.delta.chat/ has this in the code:

    <meta property="og:type" content="website">
    <meta property="og:title" content="Message privately on Delta Chat">
    <meta property="og:image" content="https://invite.delta.chat/social.png">
    <meta property="og:url" content="https://i.delta.chat">

These tags are used to generate link preview, but they come from i.delta.chat web server and we don’t want i.delta.chat web server to ever see the group names or any private data. This is why all the data like group names, invite tokens etc. goes into URL “anchor”, after #. I have previously posted about it here (follow the link in that post as well):
Onboarding centralized? [add contact with vCard, besides i.delta.chat] - #2 by link2xt

The neutral open graph link metadata might be phrased to highlight that the link can either initiate a direct message with a user, join a private or moderated group or subscribe to a broadcast channel. Improvements welcome, but an example could be:

You have been invited to message a user, join a group or subscribe to a broadcast channel on Delta Chat
