Being able to chat with a Lindy will have to be done within the Lindy at the 'Enter Message' task bar. Is that what you're referring to?
In order to do this, you'll have to share credentials at the moment, as we don't have abilities to share + collab on Lindies (yet!!).
If you're looking to simply share meeting records, you can use an 'Upload File' Google drive action after the meeting has been recorded, so the video will be uploaded to a shared space that your team has access to.
Let me know if I'm understanding your question 🙏
