Revert to previous commit

Hi,

I haven’t really used Keil Studio much other than migrate our project from the old mbed IDE, and haven’t logged in to it for about 2 years, so my memory is hazy and forgive me such a basic question.

In Keil Studio Cloud, I cannot work out how to revert to a previous Git commit and make that commit the head.

I have a commit which was made just for some testing, but i want to revert to the previous commit and move the later one to a seperate branch.

If someone could let me know step by step how to achieve this in Keil Studio Cloud that would be most appreciated.

Thanks
