Dominos.com: username/password fields are recognized, but autofill isn't working from inside page.

I right clicked the extension icon and found this collected_page_structure.json thing.
It's simply:
{
"unparsedUrl": "https://www.dominos.com/en/index",
"title": "Pizza Delivery & Carryout, Pasta, Chicken & More | Domino's",
"frames": [
{
"direction": "ltr",
"fields": [],
"forms": [],
"origin": "https://www.google.com",
"title": "reCAPTCHA",
"pathName": "/recaptcha/api2/anchor",
"uuid": "REDACTED"
}
]
}
