Power BI template App does not support On-premises data source.

We have a Power BI report, in which our data source is on-premises SQL server database, and we have around 30+ tables, and there are joins between few tables in the model. We want to create a Power BI App template to distribute our dashboard.

But template app says “It does not support on-premises data source”.

Can anybody please suggest what is the best workaround in this case?
