How can I contact repo admin?

I need to completely remove some PR, which was submitted by mistake.

Sorry, Can you provide more details?

Sure,
By mistake I have pushed some proprietary code in open-mmlab repo instead of our fork. I have closed PR, but it is still visible. I would like to completely remove it from open-mmlab repo.
PR to remove is #1675

Thanks.
