We need to add a custom role which should have edit permissions on the page but should be able to add components\create new content. The user shouldn't be able to publish content or add new pages. He can edit page and add\create relevant components\content on the page. Currently, we've added below roles to the custom role and denied 'create' permission to the role on the entire content tree except for relevant page templates and placeholder settings.
- Sitecore Designer
- Sitecore client authoring
But while adding content in experience editor user is getting 'you don't have access to add content' error. What should be the exact set of permissions to be able to add content to pages but not create pages.
