Embed report to SharePoint Online with webpart

Hi All,

I'm trying to embed a report into SharePoint Online by using webpart:

https://docs.microsoft.com/en-us/power-bi/service-embed-report-spo

The report can be displayed. However, I am now stucked at refreshing the data of the report (say, every 1 minute) without refreshing the whole page. The webpart doesn't give me much option in this.

So my question is:

1. How can I ask the webpart to refresh the displayed chart with new data? Without refreshing the whole page...

2. How can I embed a Live Page dashboard into a SharePoint Online Power BI Webpart?

Please help.

Thanks.
