A Microsoft file hosting and synchronization service.
That did not work for me. After it synced with 365 online it reverted back to the original name. Then I got an error message stating that I could only change it in Teams because it was the name of the channel. Well I created the sharepoint and didn't create a Teams channel so when I went to the Teams Channel to try to change the name I didn't have the option and received an error message to notify the admin. I am the admin. Sigh.
