What type of access must have an Anonymous user to access uploaded files?

Hi Experts

I have a process that have a pool with a form that is used by anonymous users, in this form they can get access to the records and files uploaded to the tables. In other hand I have a datalist where the same user can access to the same records but they can't access to download uploaded files, what could be the problem or what type of access I must give to this users? I'm using the cloud version of Joget

Figure 1:  This is the form that use the user in the process flow, bellow is the URL that anonymous can access to download the file without problems

Figure 2: This is the form with problems , it is called from hyperlink from a datalist , note that the user (anonymous) can access to the parent and child record, also can see the URL where to point the file

Figure 3:  When I do click I get an error message in this case
