As there is something looking as an anti-bot for downloading media files, we use a Selenium-based approach.

For `Music` tab, YouTube UI returns 3,000 entries while my reverse-engineering approach returns 5,819 entries.
For `Sound effects` tab, YouTube UI returns 400 entries while my reverse-engineering approach returns 2021 entries.

So I assume YouTube UI pagination doesn't work fine, so to retrieve all media files, the idea is to filter by `Track title` and download all entries, preferably only those that have the title we are looking for, as some tracks have the same titles.
As for `Sound effects`, even with `Sound effect`, `Duration`, `Category` and `Added` there is an ambiguity on which files do we refer to (for instance for `Truck Driving in Parking Structure`, as they all are different).
