Add attachment(.xlsx) to the webservice request using katalon

Hi Team,
How can I attach a file like we can do in SoapUI? I need to get attach a file and then use the ContentID to to run the request.

I also have an alternative where i mention the file path in the request as mentioned,

Still i will have to set the Request Property - Enable Inline Files value to true in Katalon, where i am not able to find the right steps to implement or set the Enable Inline Files Value to True.
Kindly help me out if there is a solution.
