Google Fonts families get imported when our theme is first activated inside the WordPress dashboard. If you do not see the Google Fonts families, navigate to Update Google Fonts section and click on the “Update Google Fonts” button. Note that the process might take a while, as there are quite a lot of font families that need to be imported.
If in the future Google adds a new font you wish to use and you do not see it in the font families drop down selection, import the fonts again by going to the Update Google Fonts section.
