You can use Widgets with Niagara, though if you want to use multiple you need to create a "Widget Stack" and that's a paid feature.If you only want one tho, the free version works.
Adding on to this, if you will run your VM locally, try WinBoat.It handles installing Windows for you, integrates the filesystem and uses RDP to show the app windows, so you can use them side-by-side your Linux apps instead of having to always look at the full Windows Desktop.
Thanks.
