I guess these changes in this particular file aren't required for this scrollbar issue.

[Utkarsh-123github]

Why these changes are made in this file? I think this isn't related with scrollbar issue.

Hi @Deepak-cell311 , the correction you made in components/Sidebar.tsx file and globals.css file are perfect . Good work!

But I think the other changes which you made in other files aren't required for this PR. I have dropped some comments on those files, please update this PR and ping me for the re-review or if you need any help.

Thank You!
