apply default filter based on a condition in record

Hello All,

I'm trying to create a default filter for a record type.

I'm having an array to check for the condition "IN". I should see the records for the contained items in array.

Issue here is if I dont have items in array, I should not apply that filter.

if(
isnull(
    rule returning the array,
),
{
null
},
    rule returning the array
)

what could be the solution here
