qlik sense security rules

[ali_hijazi]

Hello

I'm new to Qlik Sense

I have a stream called BI in which there are several QVF (1,2, and 3)

I have 2 Groups of Users (not created on qlik sense ; i need to know how)

Group 1 and Group 2

Group 1 can see all QVF

whereas Group 2 can see only 2.qvf

Please advise on how to accomplish this

I need to create groups of users and each group assign it access to specific QVF in one stream
