We are using a third-party service to automatically review our files for legal and brand compliance breaches, and need to be able to integrate with it so that we can keep using Monday but there is no API available to add annotations to a file. This API would allow us to work with the vendor to automatically surface these risk annotations and comments directly within Monday, and where we usually collaborate on files instead of having to be forced to another software for the review process.
It is a gap overall in the API so there are no doubt many other use cases that could benefit from it.
