Hello, I am teaching a user at our organization to create and run a simple flow that created that creates a Campaign Member, and verifies a few things. On her profile she has: Manage and Run Flow checked (via permission set I created for her called Manage and Run Flows), and has access to write, modify, edit, delete.  However, when she clicked on Activate, she got some error "You cant activate this flow because it always runs in system context." When I temporarily changed her profile to System Administrator she was able to activate it, but we do not want to have every user that wants to run this flow to be System Administrator, due to privacy reasons.

From Salesforce Support I got information that I should do the following:

1: Open the flow.
2 : Click on Save As.
3 : Click on 'Show Advanced'
3 : Under 'How to Run the Flow' select 'System Context with Sharing—Enforces Record-Level Access' (https://help.salesforce.com/s/articleView?id=release-notes.rn_forcecom_flow_fbuilder_system_mode.htm&type=5&release=224)
4 : Save it.

However, How to run the flow is not visible! Even for me, System Administrator and owner of the Flow. During the call, they had me change to Classic version - no change. This option is not available to me as a system administrator, I do not see it. I am sending a screenshot of what I see.

As a summary:

1. I, System administrator does not have option on how to run the flow
2. The user has ability to build, create, duplicate and run flows, but not activate it.

3. The user has access to create, modify, access, delete record objects that are included in the flow.
