Permitting access to specific applications of the stream

[OmarBenSalem]

Hi folks,

I have a question, I have a stream in which I have 2 apps.

I have a user who can access that stream; now I want him to just be able to see only one application of the 2 that exist.

I should then create a security rule, but I haven't figured out yet how to create it. This what I've done so far:

I should also mention that there is a security rule associated to the stream which permits to this user the full access to the stream (create, update, read etc)
how would Qlik Sense interpret these 2 rules which are "in conflict"?
And is the rule I just made correct or should I change it? if yes, how?
Thanks,

Omar,

I also tried something like this but in vain :

Any help?
