SSL VPN WITH ZTNA

Hi everyone,

Currently testing the Foticlient EMS ztna in trial,
I wanted to integrate it with our fortigate 80F on which the SSL VPN is configured for remote access of users on the herberger applications on our multi-application server which contains several application (x,y,z),
my need is to integrate ztna with ssl vpn for more granular access control, i.e. authorize a user to only access application x on the server and nothing else, anyone has an idea about this configuration because what I configured doesn't work
