email collaboration invitations directly from shared threads

want to bring someone else into the conversation, we expected to be able to just invite them via email right from that thread. Instead, we have to navigate back to the parent collection and share that entire collection with them just so they can access the specific thread we want them to collaborate on.

This creates unnecessary friction in our workflow. We often have multiple threads within a collection, and we don't always want to give someone access to everything - sometimes we just want them to collaborate on one specific thread.

We'd love to see a feature that lets us invite people via email directly from within a thread. Ideally, this would handle the permissions automatically so that when we invite someone to a thread, they get the appropriate access to participate in that specific conversation without us having to manage the collection-level sharing manually.
