I’d highly recommend a bike fit. A good fitter will be able to tell you if they can make that bike work without absurd modifications, or whether you definitely need a new frame size. Whenever a friend or family member asks about getting into cycling, I always send them straight to a competent fitter first, even if their budget is somewhat limited. It’s the most well spent money in cycling.
Some fitters seem to have extreme views, so, if possible, I would seek a fitter recommended by two or more cyclists that have a bit more experience than you in the cycling discipline of your choice. This forum is a great place to seek a recommendation, as there are probably a few from your location that check this regularly.
