Currently there is a connector for OneDrive that allows for creating share links on files:
I think it would be very useful to have the same functionality available in SharePoint. We're using SharePoint connectors to move files around during workflow, and it would be useful to have a mechanism to set grant permission to the file when the reviewer receives the approval email.
This is available for SharePoint now. However, it only scopes anonymous and organisation. It would be good to have support for individual users too (request from my customers).
You can now get a sharing link for files, read more here: https://docs.microsoft.com/connectors/sharepointonline/#create-sharing-link-for-a-file-or-folder
