How to add '$filter' in URL of HTTP Request step

Hi - I am am using HTTP Request step to call GET API.
I have to include ‘$filter’ before applying filter & unable to do so.

Expected URL:
servername/v1/Fmno/S4_FMNO_MASTER_HISTORY_API?$filter=fmno eq ‘12345’ and massn eq ‘AA’

Can anyone please let me know how to include this ‘$filter’ in Request URL.
Currently I am applying other 2 Filters fmno & massn through Parameters section, BUt API is giving output Without filters.


You parameters are to use the values as parameters in the url field…they need to be used in it

Or directly you can just use the same ur above and it should be working
