Pin Report to dashboard using Rest API

We are trying to embed the Power BI dashboard in a environment using Automated way using Rest APIs.

We are exploring new ways to improve performance for KPI loading and want to display complete KPI page as single dashboard.

Embedding the dashboard is possible with the Power BI rest API but don't see any Rest API to pin the report tiles to that embedded dashboard so seeing only empty dashboard on landing page. There is a Rest API that allow to create dashboard. But this creates an empty dashboard. Further we need to add some reports (as a Tile) into this dashboard on workspace manually.

If we get a Rest API to Pin report to a Dashboard that would be helpful for users and which reduces the more manual efforts.
