Sharing a MediaStreamTrack via getGlobal not working

[sbeatz]

we try to share a MediaStreamTrack across windows using remote.getGlobal

remote.getGlobal('shared').videoStream = desktopstream.getVideoTracks()[0];

in main.js its also still recognized as a MediaStreamTrack
but when we get it in the 2nd window via

let videoTrack = remote.getGlobal('shared').videoStream;
it is a simple object only and no longer a MediaStreamTrack

in 1st windows console we get

callbacks-registry.js:54 Uncaught TypeError: Illegal invocation
    at CallbacksRegistry.apply (callbacks-registry.js:54:1)
    at remote.js:353:1
    at EventEmitter.<anonymous> (remote.js:335:1)
    at EventEmitter.emit (node:events:513:28)
    at Object.onMessage (node:electron/js2c/renderer_init:2:9240) 

as soon as we get the track in 2nd window

isn't it possible to share the MEdiaStreamTrack via remote.getGlobal?
