Lower down the volume of specific page

I'm watching sometimes movies on my MacBook on Disney+, and I have to the volume turn up since I feel that the volume there is always a bit too low. And whenever I go back, for example, to Youtube, I've often been surprised by the volume, and I have to lower it back down.

Is there a way to automatize that so whenever I'm watching something on Disney+, the volume goes up and goes down when I leave Disney, automatically?
