How do I grant access to a datasource by datasourceid as administrator ?

There is a datasource that belongs to an employee (I think on their personal workspace). I would like to share this datasource with myself so that I can see it in app.powerbi.com and from there manage permissons for other people who need access to the datasoruce. I have the datasource id from connecting with powershell, but do not know what the next steps are.
