Script for other author's plugin listed on envato

I have added a Online Video Classes Tutoring Feature in a other author’s plugin by editing code. Can I list this file for sale on codecanyon?

Please advise.

Hi Riaz!

No, it’s not allowed to copy another’s author work then selling that item while adding some extra features.

You can find here: a useful guide about what Enavto Market is and about how to become an author.

Becoming an author on Envato Market carries certain legal implications. Everything you sell must be your own original content. If you use any assets that are owned by someone else, you must have a license that grants you permission to use and resell them.
