Display in a particular tkinter window?

[ACE0PERFECT]

I have wrote a application with GUI by tkinter. It is about optics design, and I want to use Ursina to display visualized 3D simulation in this application. So I have a Frame (or PanedWindow or Canvas, whatever) for Ursina to display. That is to say, I want Ursina display in a particular already existed tkinter component (like Frame or PanedWindow), not to initialize a new one.

I know Ursina is based on Panda3D, and I have achieved what I need by Panda3D, so I think it is possible for Ursina, but I haven't figured it out.

Here is my progress:
1 This example illustrate the need of me:
`
from direct.showbase.ShowBase import ShowBase
from panda3d.core import WindowProperties
import tkinter

root = tkinter.Tk()
root.geometry('1920x1080')

frame_panda3d = tkinter.Frame(root)
frame_panda3d.place(x=0, y=0, height=1920, width=1080)

root.update()
class Tkinter_window(ShowBase):
def init(self):
ShowBase.init(self, windowType='none')

    props = WindowProperties()
    props.setParentWindow(frame_panda3d.winfo_id())
    props.setOrigin(0, 0)
    props.setSize(frame_panda3d.winfo_width(), frame_panda3d.winfo_height())

    self.makeDefaultPipe()
    self.openDefaultWindow(props=props)

    scene = self.loader.loadModel("environment")
    scene.reparentTo(render)

tkinter_window = Tkinter_window()
tkinter_window.run()
`
This is the output:

2 I tried to transplant the above code to Ursina. But I found black margins. props.setOrigin(0, 0) doesn't work for this. I guess this is because the involvement of ursina.window(), but I am not sure. Code of this picture is a sample of Ursina. I modified it (to be exactly, ShowBase) a bit with codes in part 1.

Here is my question:
Is there a way to make Ursina display in a specific tkinter component? Or how to deal with these black margins. Thankyou
