Sharing restricted data to secure website

Hi , AlexW_82 

According to your description, you have a Pro License and you want to share your dashboard to external user who has no Power BI License.

First, in Power BI, Embed for ecternal users mainly has the following ways:
(1)Publish to Web: This is what you're using, but it does publish the report to the public network.

(2)Embed a report in a secure portal or website:

This method is to embed the current report into a secure portal, but you need to have a Power BI account to log in to complete authentication.You need to provide a Power BI account for authentication for your end users.

For more information, you can refer to :
Embed a report in a secure portal or website - Power BI | Microsoft Learn

(3)Embed for Customer:
The embed for your customers solution allows you to build an app that uses non-interactive authentication against Power BI. Your customers are likely to be external users, and they don't need to sign in using Power BI credentials to view the embedded content.

For more information, you can refer to :
Power BI embedded analytics overview - Power BI | Microsoft Learn

And for this solution, when you move to production you'll need a capacity.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,
