REST API for RLS security management and report sharing

Is there any way to handle folowing steps using PowerBI Services REST API:

1. Add members to the RLS role (Row-level security (RLS) with Power BI - Power BI | Microsoft Docs)

2. Share report with the users

I did check Power BI REST APIs - Power BI REST API | Microsoft Docs but unable to find anything useful.

We want to automate some steps to share reports with our users, so if this is not possible with REST then may be PowerShell?
