Rest API access issue for users with customer role in service desk portal

[Yellow]

I have created an jira app for 3LO Auth and given some permissions from scopes , it is working fine for the users with agent role in service desk.
But anyone who have customer role in service , they are not able to login and getting scope error because I'm using same jira app.
These are the scopes I'm using for my rest api are 

read:me read:jira-work manage:jira-project read:jira-user write:jira-work manage:jira-configuration read:servicedesk-request write:servicedesk-request offline_access
This is the  error I'm getting for customer role in service desk
