How to delete specific commit histories in Github created via file upload?

Question

I normally upload my files to Github repository through the web interface. I accidentally uploaded a file to Github repository recently and this file contains information which I don't want others to see. Now, this private info is permanently recorded in the commit history.

How can I delete this specific commit from Github?

EDIT: The commit history was created through the file upload website of github. It was not created using git.

I will answer my own question. Credit goes to sasha-dev for his comment.

Here is what I did.

• Use Github desktop to clone the github repostitory.
• Launch command-line prompt. Go to the repository folder. Run the following command;

git reset --hard HEAD~1 # remove last commit

Or the goal is to remove a specific commit, find out the commit hash

git reset --hard <commit hash>~

Next step is to force push the locally made changes to the remote github repository. Run this command;

git push -f

Commits will be removed from github repository at this point.
