I use scriptrunner to send custom notifications when solving a service request in the service desk project. The notification contains images corresponding to the user's satisfaction (from 1 to 5) and a picture of the reopen request.

I tried to use the link that is located in the corresponding transition button:
{getWorkflowButtons.call ()}https://jiraurl.ru/secure/WorkflowUIDispatcher.jspa?id=74602&action=191&atl_token=B38Y-ZHP9-M1RN-5RJC_152387e13adf686e91da5d27abcb52abab7601af_lin
But when the user clicks on it, the user goes to the main page of the customer portal service desk.
Please tell me how you can create a link so that a user who only has customer access to the service desk project, when clicking on the reopen request image, everything works correctly?
