I have a custom entity. In that entity, I have a section called 'documents' as per the below screenshot, this is an Html web resource. For now, only record owner can edit the records and other users have read-only privilege, I want to make other users can edit the documents section and save the record(only documents section, other fields/section should remain as it is(read-only)). This is on-premise
Could anyone please suggest the best way to achieve this.
