how login with customer to JSM app
i am working on JSM ,where i have two groups users(as user agent) and customers(customer can visit help center and submit help request),iam creating app ,'test_app',and set all scopes and permissions for user and for customer (like:write:customer:jira-service-management,read:customer:jira-service-management), and as admin i am giving permission from Jira Service Management Permission Scheme, like, browse Projects and create issue,the problem is when i login with my app 'test_app' as user it redirect me to my app,but when i login with as customer ,it say you don't have permission to jira site.
i want when user and customer login with my app ,user auth token store in dataase and user information also store in database with https://api.atlassian.com/me api. is any way customer login with my app and see his/her own create request.
