You can share report as Embed report:
Open your workspace > open your report > "File" > "Embed Report" > "Publish to web(public)" > you will get option for link sharable to 'email'
[if "Publish to web(public)" steps throws some error then : go to setting icon on your report > admin portal > tenant settings > export and sharing settings > publish to web > then turn on this setting with toggle button - (if toggle button already on then click 'Allow users to new embed codes']
Pros : user don't need any kind of license or even Power BI account to see your report
Cons : Data privacy issue as anyone can access your report who has this generated link.
Later on you can delete this link by : go to settings icon > manage embed codes > select your shared report link > click on delete icon
