RLS string transformation

Hi All,

I am using Embeded power BI and in that RLS we are using. In the username() i am getting a string and i need to filter the data. In the RLS i get the list of values in the form of a string. I am getting additonal characters which i don't want in order to filter the data. Could you please help which DAX function will work.

I am getting list of values as a string: "'ABC','TDEF','HIJ'"

and i should have like this "ABC","TDEF","HIJ"

Means i need to exclude the first and last character of the double quotes and replace single quotes with Double quotes. The list of values will increase. it should work dynamically
