I am unable to sell my file resources in the community

I am a user who has been using Figma for 4 years. I come from Hong Kong and shared my first resource on the community 3 months ago. I want to sell my files and plugins in the community, but I couldn’t find the price option on the ‘Publish Files’ page. I hope this problem can be resolved.
I love sharing because it can make the community active and spread knowledge to help everyone. I also respect intellectual property rights, so I hope to sell original and unique design files to the community, so that people can see their value, respect design creation, and enhance my motivation to share.
If permission can be granted, I am willing to become a community seller. If you can contact me to grant permission, I will increase the number of shared files and recommend Figma to more. Thank you very much.
