Caveat: Google Fonts, and by extension Fontsource which mostly just mirrors Googles files, strips out nearly all of the advanced OpenType features to reduce the filesize. It's worth checking the upstream version of your font to see which features it actually offers.
e.g. Wakamai Fondue lists 11 features for Googles version of Inter (some essential ones plus fractions, tabular numbers, numerators, denominators and contextual alts), while the full fat version of Inter has a whopping 44 features (too many to list, see https://rsms.me/inter/).
