How To Share access to player but only give the user ability to whitelist

so i want to share access to some people to give them ability to help me whitelisting,but i dont want them to get OP,i wanna know how to only give them ability to whitelist,not ability to OP

im inside the game whenever it start,so i want give other access to only whitelist in the aternos account,not inside the game

i know but they can also give themself OP with the access,and they can use it to grief the server and stuff
