The particles from the "Invisibility" effect make it self-revealing

When you apply an invisibility effect on yourself with the particle hiding function disabled using the /effect give @s minecraft:invisibility 1000000 0 false command, you get particles that are not really needed and that only give out that the invisibility effect is on you, which means that in this scenario you can easily be seen. I suggest slightly redesigning the invisibility effect. To make this effect have no particles at all. i.e. just make sure that when you drink a regular invisibility potion that you brewed on a regular potion maker, you don't have any particles at all, even if the particle hiding feature is disabled in the NBT tags of the potion. And the same thing with the commands: if you now apply the “Invisibility” effect on yourself using the command /effect give @s minecraft:invisibility 1000000 0 false and disable the particle display function, then you will have particles from the effect, but if you use a slightly different command /effect give @s minecraft:invisibility 1000000 0 if true, then only then you won't have any particles. That's why I suggest making everything easier and changing the “Invisibility” effect for the better: just completely remove the particles from this effect from the game code, and remove the logical values “True“ and ”False" when entering the /effect command, too, i.e. they are also essentially useless.
