Adding HTTP header to outgoing requests

[swapnikap]

I am trying to play DASH format videos with WIDEVINE and FAIRPLAY DRM support in my angular application.
For that, I need to add headers and some extra query parameters to the HTTP requests.
Below is the link, that the DASH player is supporting intercepting HTTP requests.

Please help me, with how to invoke RequestModifiers with Vimeo-js player.
