Hi @Anonymous,
Just to validate. With activate you mean who triggered an existing flow on the list? If yes, this should be possible. You can get the user name of the identity which triggered the flow from the headers.
Below is a small example to demonstrate.
1. Create a flow with the SharePoint For a selected item trigger. Configure it to use a specific list, in this case Captureuser
2. Add a Compose action and add the following expression to it:
triggerOutputs()['headers']['x-ms-user-name']
3. Make a Note of your flow Id
4. Add a button to your list, in this case the CaptureUser list. Create a column called Button (type single line of text). Add the following json to it and replace the flow id by your flow id. This way you can click that button and trigger your flow.
