Row Level Security with Multiple levels (Complicated)

Hi,

I am looking to implement RLS for multiple levels.

I have 2 tables as below.

1) Groups

2) Tasks

Groups table will have , Group name and Member email.

And tasks will have below columns

Upon login by the user i want to filter my report in below ways.

Rule: 1) all the records should be visible wherer Isrestricted = NO for every user.
Rule 2: 2) Up on login by User, Rule 1 above should be applied and also, Isrestricted group = Yes and it should look at group table who is the user and how many groups the user is part of and only those groups in Tasks table should be filtered.
Rule 3: 3) Irrespective of above, who ever part of submitted by in the tasks table they have to see all the submitted by records along with Isrestricted access = NO.

I have tried relaly very hard to crack this and finally coming here for help from great minds.

Attaching the PBIX for your perusal. Appriciate your help guys.
