dax calculate & max value

[Anonymous]

Greetings to all, I hope you are well
I am again in the forum with a query, which I suspect can be resolved with a simple dax formula, but I have not yet managed to solve.
in my facts table I have records that represent a theft event for each department, the measure I used to add it was simply a count of rows with "countrows"
Now I would like to place a card with the department that has the most theft, and that this is not affected by the filter context
try to do it with "calculate" and "max" "max" but I do not know how to combine them to get the result I want.
I hope some of those present can help me. Thanks teachers

try this MEASURE

Measure =
CONCATENATEX (
    TOPN ( 1, ALL ( TableName[Departamento] ), [Cantidad], DESC ),
    [Departamento],
    ","
)
