you could try using WebCallbacks which is commonly used to resolve promises:
https://cs.chromium.org/chromium/src/third_party/WebKit/public/platform/WebCa...
One example would be in the Presentation API implementation:
https://cs.chromium.org/webrtc/src/third_party/WebKit/Source/modules/presenta...
