(async()=>{

//
//  requires service account token
//
//


        var token     = '';
        
        var project   = '';
        var service   = '';
        

        
  //list service details
  
  
        var url       = `https://run.googleapis.com/v1/projects/${project}/locations/us-central1/services/${service}:getIamPolicy';
        var headers   = {
              authorization     : `Bearer ${token}`,
              'content-type'    : 'application/json'
        };
        
        var res     = await fetch(url,{headers});
        var json    = await res.json();
        
        console.json(json);
        


  //make public
  
        var json    = {
              policy    : {
                    bindings    : [
                          {
                            role      : 'roles/run.invoker',
                            members   : ['allUsers']

              }
        };
            
        var url       = `https://run.googleapis.com/v1/projects/${project}/locations/us-central1/services/${service}:setIamPolicy';
        var headers   = {
              authorization     : `Bearer ${token}`,
              'content-type'    : 'application/json'
        };
        var body    = JSON.stringify(json);
        
        var res     = await fetch(url,{headers,method:'post',body});
        var json    = await res.json();
        
        console.json(json);
