Bootstrap 5 how to center a div with a VKontakte widget?

Question

css

At work, I had to do a little backend, although as a rule I don’t do this.
For the design of the business card site, I chose bootstrap.
At the bottom of the page, I should have a VKontakte widget, in fact it represents itself as a div.
I have this div in another one with the row class. Inside it there are other div elements on the grid.
What class should I add to the div class=row so that the VKontakte widget is in the middle? Interested in the standard Bootstrap solution without adding your own CSS styles.
