Problem with notification multimedia with cast

Issue description:

hello, when i cast my song to a google nest audio for example, it appears well into the symfonium app, but in the multimedia notification of my android 15 there is a button called this device or other device if the cast is running to a cast device, this button is disabled and transparent why ? i think it is the MediaRouter API no ?
it’s possible to add this feature in the future release ?
