Log in to the Power Automate cloud portal (Microsoft Power Automate), select 'Desktop flow', choose the flow you wish to share, click the 'Share' button, enter your colleague's name, and share it with the option 'Run only user', as shown in the screenshot.
Note: It is assumed that you possess a premium license and can access the Power Automate cloud portal using the same credentials as your desktop flow.
