When a Automation is created, it is being created in the personal space. If another users needs to access the same automation and trigger it on demand, they have to create a duplicate of that Automation from hub or change the owner of the Automation in QMC and check for the connections created in all the other connector blocks. It would be very effortless and engaging if all the users can get hold of the Automations irrespective of the space it is in.
This reduces the effort in duplication of Automations and managing connections in all the other connector blocks.
