Make a public form link unshareable

in the Url, capture the time when this was clicked: 

now = zoho.currenttime.toString();
nav = "https://creatorapp.zohopublic.eu/podmanagement/pod-planner/form-perma/Fire_Risk_Assessment_Residents/740aNxP1kK7AgbezOM1NBtqNmQ78bMC7YrrSg3Jy0MsEGu4m8EYKw3e4rsfsZFrXKNSffrgd0mZB7Jk4Amv5K0xNemxhutH4Gqsp?Developments=SitePath&time=zctime";
navnew = replaceAll(nav,"SitePath",txt);
navnew2 = replaceAll(navnew,"zctime",now);

in the form that will load, add this before the script is run so that it gives a 5 second window for the URL to load or otherwise it will not load: 

dat = input.time.addSeconds(5);
//
if(zoho.currenttime < dat)
