Insert filter from text originally on quotes

Hello, 

I am trying to use this filter for specific categories in a column 

Count = CALCULATE(

        COUNT (Table[column])

        ,  Table[Column] IN {Cat1, Cat2, Cat3}

    )

However, the categories in the column are enclosed with quotes and have a “=“ sign like shown below

When I try to insert these names in the IN function, between quotes like IN {“= “N””),  PBI doesn’t understand the syntax. Can someone help me?  

Thanks in advance
