On the old and outdated version of the official Minecraft Launcher you could remove the requirement for Java 8 and instead use versions such as Java 16, ever sense the migration of launchers, this seems to have been removed and when trying to launch with Java 16 the launcher refuses, even though the game does not, in the way I run the game and most likely other Players may face this too and don’t want to use Java 8 or are also required bot not to. To fix this issue you would only need an option to use any JDK, it would allow The Use of the MS launcher for people who need to use Java 16

AFAIK it maybe be Windows only.
