Granting access a custom function to a role

Hello.

I made a new custom package to make a custom lobby as it’s way too complex to make it on IFS.

I made custum functions in this new package to return results, but they are not available for users. What’s the way to grant access to these custom functions? 

I went to this screen :

ifswin:Ifs.Application.SecurityAdministration.PermissionSetDetail?action=get&key1=XXXXXXXX

I selected the database objects tab, I ran a research to my new package name and IFS listed it, but I cannot find every custom function inside, 1 custom function is listed out of 3.

Am I doing something wrong?
