Hi @ Gandharbika,
Could you please share a screenshot of the configuration of your flow?
Could you please share a screenshot of the run details of your flow?
Do you want to refresh the SharePoint list items though Microsoft flow?
Or do you what to update the SharePoint list items though Microsoft flow?
If you want to refresh the SharePoint list items though Microsoft flow,I afraid that there is no way to achieve your needs in Microsoft Flow currently.
You could only refresh the SharePoint list items from sharepoint site use shortcut keys "F5" currently.
Refreshing the SharePoint list items is not supported in microsoft flow currently.
If you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

If you want to update the SharePoint list items though Microsoft flow,you could use the "Update item" action to achieve your needs,and then you could go to sharepoint site to use shortcut keys "F5" to refresh the site.
Please let me know if your problem could be solved or share more details so we could provide a proper workaround for you.
Regards,
Alice Zhang
