Have you deleted a flow accidentally and want to restore it yourself without having to file a support ticket with Microsoft Power Automate Support? You can now use Admin PowerShell cmdlets to list the deleted flows in the environment and restore it using Power Shell script. Please follow the detailed walkthrough documentation here Restore deleted flows with PowerShell in Power Automate - Power Automate | Microsoft Docs.
Note: You should be an admin to install PS modules and run the scripts. If you are not an admin, please reach out to your admin to restore a flow on your behalf.
