To post as an organization on LinkedIn the OAuth2 connection will request the scope that is
mentioned in the error message (w_organization_social) which your app doesn’t have permission for. To get that, your application
needs to be put through LinkedIn’s Community Management App Review process.
This can be turned off in the credential settings by toggling the “Organization Support” option. You can find more information about that in our documentation).
Perfect! It works now only if I understand correctly I can not make a post on my business page unless I do it via the community management app review process?
It is now connected I should have unchecked those 2 bottom checkboxes.
