What tool should I use to split git commit into multiple ones?

Question

For IntelliJ I use this workflow:

Open the git log window or Alt + 9
Right click on commit you want to split → Interactively Rebase from Here
Right click on commit you want to split → Stop to edit or Alt + E
Start Rebasing
Right click to the current commit in the git log with the yellow label 🏷️! → Undo commit… alternatively execute git reset HEAD~1 in the terminal
Ctrl + K to select and commit your changes with the according message. Repeat as often as necessary until all changes are committed.
On the bottom right click: Rebase Stopped for Editing → Continue
