So please share me link how can I do it? If I can do it directly from javascript like below

configString=document.getElementById(„Conv1ServersideTagging.config.containerConfig“).value;
regionId=document.getElementsByClassName(„sw-single-select__selection-text“)[1].innerText;

                if(regionId=="")
                {
                	alert("Please select value in Region");
                	this.isLoading = false;
                	if(document.querySelector('[name="Conv1ServersideTagging.config.region"]').classList.contains('error'))
  		document.querySelector('[name="Conv1ServersideTagging.config.region"]').classList.remove('error');
                	else
                	  document.querySelector('[name="Conv1ServersideTagging.config.region"]').classList.add('error');
                	return false;
                }
                if(configString=="")
                {
                	alert("Please enter value in Google Tag Manager (Server) Container Config");
                	this.isLoading = false;
                	if(document.querySelector('[name="Conv1ServersideTagging.config.containerConfig"]').classList.contains('error'))
  		document.querySelector('[name="Conv1ServersideTagging.config.containerConfig"]').classList.remove('error');
                	else
                	  document.querySelector('[name="Conv1ServersideTagging.config.containerConfig"]').classList.add('error');
                	return false;
                }
