Trouble shooting adding Inter font

Hello,

I'm wondering if Squarespace supports variable fonts and i am struggling to add Inter

Here is my bit of coding and i'm hoping one can help troubleshoot and/or highlight an oversight on my part:

@font-face {

    font-family: 'Inter-VariableFont_slnt%2Cwght';

       src: url('https://static1.squarespace.com/static/637b634116b577075011d202/t/642ed6b68ec3b83bb56b3084/1680791224227/Inter-VariableFont_slnt%2Cwght.ttf');

  }

Hi,

What is site url?
