[[1.16.2]Need help with Potions]

Hi everyone,

I'm very new in coding and i thought it's a good idea to start with Minecraft modding. A lot of my things work but one thing doesnt work:

I tried to give me Godmode with Regeneration but i dont get the Potion. So can anyone help me with my code?(Please an example code)

And sorry for my bad english ._. Here is the code:

 

import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.potion.Effect;
import net.minecraft.potion.EffectInstance;
import net.minecraft.potion.Effects;

public class Godmode {
    public static PlayerEntity Player = Minecraft.getInstance().player;
    public static boolean Toggle = false;
    public static void Regeneration() {
        if(Toggle){
            PlayerEntity Player = Minecraft.getInstance().player;
            EffectInstance EffectInstance = new EffectInstance(Effects.REGENERATION);
            Player.getActivePotionEffect(Effect.get(20));
            Toggle = false;
        }else{
            Player.removeActivePotionEffect(Effects.REGENERATION);
            Toggle = true;
        }
    }
}
