viewer preset not showing up
Issue : when the user from author group tried to author dynamic media in page, it found that the component is not showing the viewer preset ddl. It is just showing the option "NONE". when I checked, I came to know that under Tools->Assets->viewer presets we need to create / change the state of preset. But for this user I couldn't find a option to create it. But I understood that viewer preset can only created by administrator. Since this user is not an administrator the create option is not showing up for this user. But when I tried with another user who is not in admin group is able to view the preset under tool->assets->viewer preset. Also the user is able to author the DM component by selecting the viewer preset option.
Then I compared the author with this user, found that author has no permission under conf/settings/dam/content/viewerpresets. I've provided exactly what I've observed with other user for whom it is showing up.
What would I possibly missing here in order to provide the author to view the preset under assets->viewer prest and DM component has to list down the ddl correctly?
user belongs to author group has the following view. Nor create neither view it. Thus viewer preset option is not coming in DM component.

user belongs to brand admin, able to view it but can't create it. viewer preset ddl is coming up in DM component.

An admin user can view/create/delete/enable/disable it . viewer preset ddl is coming up in DM Component.
