The layout includes a navbar, side panel, and main panel for displaying data. I have nested rows and am trying to display 3 cards in the last nesting that fill the entire remaining width, but they are currently stuck to the left side:

I am attempting to center rows of 3 cards in the Main panel space, but currently, they appear shifted to the left side. You can see it more clearly with the black background applied. The layout is meant for desktop viewing, without responsiveness.
