When the 'Share - File names' setting is in enabled, we share with teammates the filename of the document in which you are currently working.
How does it work?
This feature works by looking at the document title of the currently active window.
This feature is currently limited to only a select category of apps and websites:
JIRA - shows current ticket title and ID from web
Bitbucket (Including PR descriptions being reviewed)
GitLab (Including PR descriptions being reviewed)
