The admins should be able to work on automations even if another user created them. If an employee leaves the company and he created an important automation, I have to rebuild it if I want to change something. Besides that: I have no clue what these automations really do. An angry ex colleague could send emails to his private account like "won deals" from my company. At least, I should be able to duplicate these automations.
Please do not hesitate to ask me if you have any questions about it.
