Streaming URL - OTT service player CORS issue

Hi, Our client would like to use a number of channels from [login to view URL] and have them played in an Angular web app, iOS, and Android. Streaming URL example: [login to view URL] Due to the CORS issue, this is not possible so we would like to work with an OTT expert to achieve this without having to self-host all these channels ourselves. We have an Angular Ionic app ready to test any player/code to be used to achieve this. We will provide more extended work for the successful candidate to help us with casting and ads before the play function.
