DAX help combining 2 RLS Filters

[ptmuldoon]

I'm still learning more on how to use Dynamic RLS with Filters to isolate only the particular data and rows for user.   And I found this article this morning that has been very helpful and useful.

Power BI Row Level Security RLS Setup | Step-by-step guide (biconnector.com)

And I have this half working at this point based on my data and tables.  But I'm wondering/hoping if there is way to combine the below 2 filters into 1?

I can get the data to filter on each one separately (GL Accounts Table).  But I want to try and combine the two together if possible. 

CONTAINSSTRING(
    MAXX(
        FILTER(
            Users,
            Users[Email]=USERPRINCIPALNAME()
        ),
        Users[GLCategories]
    ),
    [GL Category]
)


CONTAINSSTRING(
    MAXX(
        FILTER(
            Users,
            Users[Email]=USERPRINCIPALNAME()
        ),
        Users[Departments]
    ),
    [Department]
)

This be an And && condition, where both conditions must be true.  

And thank you again for any help.

&&

CONTAINSSTRING(
    MAXX(
        FILTER(
            Users,
            Users[Email]=USERPRINCIPALNAME()
        ),
        Users[Departments]
    ),
    [Department]
)

Combine how?  Do they both have to be true ( "&&" ) or can either be true ( "||" ) ?
