How do I turn the free forge app into a paid one?

Hello,I have some questions to ask. The questions are as follows:

  1. When the free app has been reviewed by atlassian and released to the market,How can it be converted into a paid app?

  2. When the free forge app passes the review of Atlassian, I add the license,and the following errors will be reported when it is installed in the production environment. So how can I solve it?

▶️  GraphQL https://api.atlassian.com/graphql
Query: 
      query forge_cli_getInstallationTask($id: ID!) {
        appInstallationTask(id: $id) {
          state
          errors {
            message
            extensions {
              errorType
            }
          }
        }
      }
    
Variables: {
  "id": "dfdf6970-cc4c-44ba-8860-b5c29e3b949c"
