How to make it mandatory to upload a file when creating a document?

In Athento it is possible to activate that the binary or file of any type of document is mandatory at the time of creation. To do this we need to go to the form configuration.

When entering the form in the configuration tab, in the basic configuration section, there is an option "Requires document", we must activate the option (It should be displayed in blue color).

In this way, when the user creates the document from the modal (+), he/she must load the binary or file to continue with the creation.
