I built a flow to create a contract on an opportunity record. Then I put a button inside the opportunity page layout that launchs the flow. Now Our Partner community users can see the button , but when they use it an error occurs. How Can I make the flow available for partner community users?
Thank you for help me

Sorry now below you find the stamp of the error page:
