Users Authorization in SAP UI5 launchpad

I have configured a Launchpad using .xswidget(catalog) and .xsappsite(launchpad) files for my UI5 project.

Currently, I have added 2 tiles to launchpad. I want to restrict user(s) to see authorized tiles.

for example, User A should see only 1st tile

                     User B should see only 2nd tile

                     User C should see both tiles

How can I achieve this?

Thanks,
