I am designated to write an API, that serves images, possible BLOB types, which then will be consumed by Business Central and then saved into Document Attachment table. The Document Attachment table does not store the actual content of the file just the name and extension of it and other generic description stuff. I want to know the type in which content of the image is saved in Business Central's Document Attachment table so that I can write an Azure function that serves images converted in that type.
