Currently, attachments (images/files) in a collection item field can either be deleted manually within the collection, or we can use the PATCH command to update/replace the attachment via API.

However, there is no direct API call to delete individual files remotely.

What we need is a new API call to be able to target using fileId information so files can be removed.

e.g.

https://api.webflow.com/collections/580e63fc8c9a982ac9b8b745/items/581d2d8256e14ea22daf82df/fileId/60b6f457e8e7d557ef46dcef
