You can type on the page (you can use this to fill form fields).
Browsershot::url('https://example.com')
->type('#selector1', 'Hello, is it me you are looking for?')
You can combine type
and click
to create a screenshot of a page after submitting a form:
Browsershot::url('https://example.com')
->type('#firstName', 'My name')
->click('#submit')
->delay($millisecondsToWait)
->save($pathToImage);
