Dynamic filter using lookups

I'll start by saying I'm new to PowerBI. I've used Tableau and know I can do what I'm trying in that tool but in PowerBI it seems, less able.   I have a table of projects, those projects have owner...

    You can achieve this in Power BI using DAX — it just requires a different mindset than Tableau.
    Instead of a boolean filter, you can create a measure that checks if a project is owned by the selected manager’s team, either directly (project owner) or indirectly (task owner).
    For example:
    ShowProject =
    VAR SelectedManager = SELECTEDVALUE(Users[Manager])
    VAR ManagedUsers = FILTER(Users, Users[Manager] = SelectedManager)
    VAR HasDirectOwnership =
    Projects[OwnerID] IN SELECTCOLUMNS(ManagedUsers, "UserID", Users[UserID])
    VAR HasTaskOwnership =
    COUNTROWS(
    FILTER(Tasks,
    Tasks[ProjectID] = Projects[ProjectID] &&
    Tasks[OwnerID] IN SELECTCOLUMNS(ManagedUsers, "UserID", Users[UserID])
    )
    ) > 0
    RETURN IF(HasDirectOwnership || HasTaskOwnership, 1, 0)

    Then use this measure as a visual-level filter (ShowProject = 1).

    It gives the same effect as your Tableau logic — filtering projects dynamically based on the selected manager and their team.

    For a similar concept and more details, you can also check Microsoft’s official documentation on Row-Level Security (RLS) in Fabric:

This is very close, I've tweaked it and it is almost working but I'm having problems with the task ownership piece. I've played with the formula and it does product the correct counts of rows with task owners on a project when I isolate the countrows bit minus the select columns based on user name but the problem is once I apply that and run the whole thing it only selects rows when a person on the manager's team has a task on the project. I want it to still have a count when the person owning the project is outside of the managers team. I think what's happening is the tables are being filtered down so much that the available projects in the "programs" table is already filtered down prior to the count running. The problem is I can't figure out how to get it to go first. 
Show Project =
VAR SelectedManager = SELECTEDVALUE(Managers[Manager])
VAR ManagedUsers = FILTER(Managers,Managers[Manager]=SelectedManager)
VAR HasDirectOwnership = MAX('planview rpt_programs (3)'[tech_prog_mgr]) IN SELECTCOLUMNS(ManagedUsers, "UserName", Managers[User Name])
VAR HasTaskOwnership =
COUNTROWS(
FILTER( 'planview rpt_raid', MIN('planview rpt_programs (3)'[primary_key]) = 'planview rpt_raid'[parent_task_key]
&& 'planview rpt_raid'[resource] IN SELECTCOLUMNS(ManagedUsers, "UserName", Managers[User Name])
)
)>0
RETURN IF(HasTaskOwnership|| HasDirectOwnership , 1, 0)

Remember that your FILTER is applied on top of the current filter context. Better use

VAR ManagedUsers = FILTER(ALL(Managers),[Manager]=SelectedManager)
