Slicer with Month year filters visuals accordingly for last and current month

I have a slicer where I select month (from table Dates Calendar) and for example if I choose march 2023 I want to have two gauges filtered adequately, one for last month - february 2023 and the other one for current month - march 2023.

As in the picture shown that date chosen is Dec-2022 and each gauge to be filtered by this slicer accordingly for last and current month, how can I achieve this?  Measure inside Gauge is: Sum(Bad Actors[time])/sum(Bad Actors[all actors]).

In other visuals I have been using for such filtering measure that I created:

Last Month =

Var _max=Max('Dates Calendar'[Date])

Var _end=EOMONTH(_max,-1)

Var _start=EOMONTH(_max,-2)+1

Var rs=IF(Max('Calendar'[Date])>=_start &&

    Max('Calendar'[Date])<=_end,

    1,

    0

    )

    Return rs
and I was adding this measure to the filter pane : Show items when the value is 1, but for this visual it doesn't work.
