Since you are using a USB mic directly into a laptop, you can easily "test" whether or not buying a vocal booth or room treatment will change anything for you....

Sit in a closet full of clothes (pushed to either side of you).
Or drape a heavy quilt or a couple of blankets over something to make a "tent".
Record something in there. It will be just as effective as an isolation booth.
See if it makes a difference.

From what I've read about your microphone, it doesn't pick up much other than what is RIGHT in front of it. The reviews I read said you have to be pretty close to it to get a full sound. And, not many of the reviews seemed to be from people recording vocals for music. More for podcasts and gaming narratives. (Though there were some who thought it worked well for vocals).

If you are serious about recording music, I'd investigate microphones and spend your money there instead of room treatment or isolation booths. You also might consider the smallest Focusrite interface - which includes nice preamps - though that would mean a different mic - since it won't take a USB mic (I don't think).
