Solution for unsupported features of postman

Hello,
I am using postman-to-k6 to convert my postman collection to k6 script
But the issue is as pm.request.body is unsupported feature and and I want to use it in pre-request script.
and pm.request.body.update as well want to use is there any solution for it?

The postman-to-k6 converter is no longer maintained by us, it was adopted and moved to GitHub - apideck-libraries/postman-to-k6: Converts Postman collections to k6 script code

I am not sure if they follow the community forum, so you might need to look through the issues there and potentially open a new one, if this doesn’t already exist.
