Hello SSVK,
i have managed to get the users sharepoint groups using flow by using send HTTP Request to sharepoint:
_api/web/SiteUsers/getbyemail('@{triggerBody()?['Author']?['Email']}')
Then using also Send HTTP Request to Sharepoint, get the users group as below:
_api/Web/GetUserById('@{variables('CreatedBy')}')/Groups
And HYG you get all the groups the user belongs to 🙂
