How to open Approve.aspx from SharePoint ONline Site using Power App Forms?

[Avian 1]

Hello,

I want to open approve.aspx (see below image) from SharePoint Online using Custom Button in Power App forms. I used Lanuch as mentioned below, it is opening in new tab instead of modal dialog form (see below image)

launch("https://mysptest.sharepoint.com/sites/AvianTest/_layouts/15/approve.aspx?List=%7B1e3329c5-f919-47f6-...")

Let me know what I am missing here? 

Regards

@Avian 1 the launch function only has options for replace (i.e the current screen) or new. There is no option for opening in a modal window.
