How to create a jump boost game pass?

I have been having trouble creating a jump boost game pass, I have looked all over the internet for solutions but didn't find any

You have to create a gamepass. Add a severscript. When a player joins it fires a function: it checks if player has the gamepass if so then plr.CharacterAdded:Connect(function(char) --- fires when char is added -- now make humanoid jumppower go up by an amount that you want.

These are the instructions you have to script the real thing.

Would appreciate an accept if it helped.

Or you can use a gravity coil if that's good? You can even mess around with it and delete the sound of the gravity coil and also make the gravity coil invisible! If you would like to use this method here then here are the instructions: Add the actual gravity coil I recommend my one as its all setup and its invisible :) and there is no bounce sound either! Here is the link:

1)Put your gamepass ID into line  of the "ServerScriptService" script
2)Put the "ServerScriptService" script into ServerScriptService
3)Put the "JumpCoil_put_in_serverstorage" into ServerStorage

THESE INSTRUCTIONS ARE ALSO IN A SCRIPT IN THE FOLDER Please accept my answer if it worked :)
