AppStream 2.0: users applications assignment

Hi Yes, You can restrict the applications to specific user via App entitlement. However it uses SAML assertions. The key considerations are

• you should give Appstream view rather than desktop view .If you are giving the entire desktop to user, then user will be able to open it. Controlling the app view inside the desktop can be achieved using NTFS permissions.
• You should use third party SAML for authentication with the attributes defined and added to App entitlement in the stack. Refer https://github.com/awsdocs/amazon-appstream2-developer-guide/blob/master/doc_source/application-entitlements-saml.md for more information.

Let me know if you are stuck , happy to troubleshoot
