Copy current 3D model mark to a file

[LyonMNGIS]

Hello,

How can we export a 3D model mark from an existing ArcGIS Pro project?

In the example below a 3D model mark is used to draw Azalia bushes. I want to copy this 3D model mark so I can use it in other projects. I can change the 3D model mark in the symbology tab, but it does not identify the current 3D model mark.

Thank You!
