How to create a QSGTexture (Metal and d3d) with new rhi backend (Qt 5.15)

[dashandslash]

The title is quite self explanatory, I need to create a QSGTexture for the two different api (Metal and d3d).
For opengl I used to call:
auto qsgtexture = qwindow.createTextureFromImage(....)

This seems returning a nullptr if the scenegraph is initialized with a different backend from opengl.

What is the best new way to create such a texture with the new Rhi?

The follow up question would be, can I give the returned QSGTexture to a QSGSimpleTextureNode using node.setTexture(qsgtexture);?

I am currently working with the latest Qt 5.15

Thanks
