Can’t get this font to show up in the light version

Hi there, I cannot get this font, Fraunces, to show up in the Thin 100 weight.
https://fonts.google.com/specimen/Fraunces

I would like it to show up in my H2, looking like Fraunces-Thin-100.

Under Quick CSS I have pasted:

h2 {
font-family: ‘Fraunces’, serif !important;
font-weight: 100 !important;
font-size: 38px;
text-transform: none !important;
}

The font family, font size, all work well with that CSS code, but not the font weight, trying to get it to be Thin 100.

Would you have any ideas? Thank you!
