Hi @kack l ,

If a flow needs to run with elevated permissions, a developer can set the Run As flow property to System User.

Flows can run as the:

• User who initiates session: The flow runs as the user who triggered the flow. For example, if a flow executes when a record is created, the flow runs as the user who created the record.
• System User: The flow runs as the System User. The System User is not a user record from the User table. System is a service account that is not restricted by access controls.

Thanks,

BK
