Power BI reports from SharePoint Online list - security considerations

Hi,
I have created Power BI reports using SharePoint online list datasource. After publishing to the web, I have embedded my report in a SharePoint online page.
There is a share icon at the bottom of the report which allows users to share the report link with any external entity. I was able to access that report using the share link while not connected to my organisations network.

Is there anyway I can secure access to those reports and share them on my SharePoint online sites without allowing users to share them?

Thanks,
Shruti
