How to display the permission groups of an item within a Sharepoint Online list with JavaScript

I have a list of Sharepoint Online, the items broke the inheritance and I need to show them with their respective permission group in a table on a blank Sharepoint page.

In the following code I show the group of permissions that the list has in general,

You can help me perform the same procedure but for each of the items

function getListPerms() {
            var clientContext = new SP.ClientContext;
            var siteColl = clientContext.get_site();
            var site = clientContext.get_web();
            listSecurableObject = site.get_lists().getByTitle("MyList");
            listRoleAssignments = listSecurableObject.get_roleAssignments();



clientContext.load(listRoleAssignments,'Include(Member)');

        clientContext.executeQueryAsync(Function.createDelegate(this, this.getListPerms_onQuerySucceeded),Function.createDelegate(this, this.getListPerms_onQueryFailed));
   }
