Show Another Website in My Pages on ReactJS

I want to ask a question .. I made a website using ReactJS, the contents of the starting page are Menus and when I click on one of the menus it will lead to a page with a Link from a website accompanied by several parameters. Example:

https://example.co.id/run?_pages=Stock.rptdesign&Group='+this.state.Group+'

Now I don't know how to call a Website with a link like that on ReactJS.

Please help. Thank you
