give it an autoFocus (camelCase because its react/jsx) attribute

<input type="text" autoFocus/>

if thats what you mean.

The autoFocus attribute is a boolean attribute.

When present, it specifies that an element should automatically get focus when the page loads.

Try this

Use event.target.focus instead of click. You might also want to [invoke this at the end of the event loop][1], i.e. after a timeout of 0ms:

const onBlur = (e) => {
  window.setTimeout(() => e.target.focus(), 0);
};

return (
  <div className="App">
    <h1>Hello CodeSandbox</h1>
    <input type="text" onBlur={onBlur} />
  </div>
);
