I am trying to find an element within a using testcafe but i am unable to do so. is there a method to get this done please?

i have tried the following :

t.switchTo("frameID");
var ele = Selector("#ele");
await t.click(ele);

another attempt :

Selector(() =>{document.getElementById("frameId").contentDocument.getElementById("#ele"));

This throws the following error : Function for selector should return DomElement, NodeList, HtmlColection, NULL or undefined.
