The two basic things you can do is buy a longer stem and/or move the seat back, possibly with an offset seat post if needed. As you move those two contact points farther apart your riding stance will drop so you should be aware of that, perhaps needing a more acute angle in the stem to compensate. If you already have the bike, the longer stem is a pretty cheap first step to see what's what. You could also experiment with some different bars which move the hand positions back, but at some point, if it doesn't fit it doesn't fit.

Sometimes discussion about frame sizing and fit can get a little crazy as if most people can tell the difference between a cm or two and not recognizing that human bodies have varying torso and leg lengths for any given height. I think it's more important to just use the numbers as a rough guide and actually see if a bike fits. People also manage to ride a lot of varying positions too. Tri riders have seats forward, road bikes tend to currently be on the small size and positions range from hunched over to upright. I flip flop with no problem between my commuter, gravel and road bike which all have different geometries and fit.
