Power Apps forms for SharePoint launched from a list webpart on a page

I created a Power Apps form for a SharePoint list. I am using webparts on a page for users to interact with the list and form. When opening the form from the webpart on the list, the form doesn't function the same as it does directly from the list.
1. Can the custom form open in a dialog or from the right (basically not navigate away from the page to open the form) from a list webpart on a page?
2. After someone accesses the custom form from a list webpart on a page, what is the best way to have them go back to that page after they click Save or Cancel on the form? There are several pages the list webpart will be accessed on, so it needs to account for that.
