You could put it up on the center stand, add some weight to the seat if necessary, and spin the front wheel. If the wheel is bent or wobbles, you'd need to get it straightened or replace it. Take a look also at the tire, as the sidewall could have gotten damaged, and is now bulging out from normal. In that case, replace the tire before it fails while you are underway. That would be not good.
The wheel may be bent at the rim, which may be correctable after removing the tire by judicious use of a hammer.
If there is any radial or axial runout, you will likely get wobble in the steering such that it is uncomfortable, not to mention dangerous. If the wheel is too damaged, replace it, ditto for the tire.

I checked the front tire and didn't see any issues with the front tire. No wobbles or anything. Can anyone tell me the difference between scooter vibration and just normal oscillation please.

Danielle have you checked the rear wheel as presume that followed through into the pothole as well and there is more weight there with rider and engine. Check wheel /tyres as suggested and see if any side to side play in engine mounting bushes by moving engine side to side when holding the rear wheel.

The rear tire & wheel can be checked for 'round' and vibration by setting up on the center stand, starting the engine, and opening the throttle. The clutch should engage, and start the rear wheel spinning.
You can watch the outer diameter of the tire to see if it is concentric with the axle. If not, it will appear to be moving up and down. You can check axial runout by holding a pencil or other next the rim of the wheel. As it rotates, it should maintain a fixed distance from the end of the utensil you are holding. If it appears the rim gets closer and farther apart as the wheel rotates, likely the rim is bent.
If you spin the rear tire fast enough you may find that the wheel & tire are out of balance, and the combination will vibrate and start to shake the seat up and down, and the machine will start to 'walk' on the center stand instead of staying in one place. That generally indicates an out-of-balance condition.
