 ### Error: Resource not accessible by integration
 
-This message means the requester does not have enough permission. If `secrets.GITHUB_TOKEN`
-is explicitly passed, this problem can be solved by just removing it.
+This tool requires write permission, and that message means the requester does not have enough permission.
+Recently, GitHub sets permissions conservatively for newly created repositories. If it's a newly created repository, check your Settings > Actions > General > Workflow permissions, and make sure to enable read and write permissions.
+
+Then, you can specify permissions for the job like this:
+
+```yaml
+permissions:
+  pull-requests: write
+```
+
+For more detailed information about permissions, you can read from the link below:
