Figured this out for LinkedIn :)
javascript:(function(){var i=0;var f=function(){
let l=document.getElementsByClassName('artdeco-button artdeco-button--muted artdeco-button--3 artdeco-button--tertiary ember-view invitation-card__action-btn')[0];if (!!l){setTimeout(function(){l.click();}, 100);setTimeout(function(){
document.getElementsByClassName('artdeco-modal__confirm-dialog-btn artdeco-button--primary')[0].click();},2500);setTimeout(function(){f();},2500);}};f();})()
