How to mount colab to different google drive

I have mistakenly mounted the wrong google account while using the authorization link. How can now I change it to the one I intend to use? I have tried restarting the runtime, but it’s not working.

from google.colab import drive
drive.mount('/content/drive', force_remount= True)
os.chdir('/content/drive/My Drive/DFU')
Mounted at /content/drive
---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)
<ipython-input-4-4c99a186fa70> in <module>()
      1 from google.colab import drive
      2 drive.mount('/content/drive', force_remount= True)
----> 3 os.chdir('/content/drive/My Drive/DFU')

FileNotFoundError: [Errno 2] No such file or directory: '/content/drive/My Drive/DFU'

I would recommend to post this question to a Google Colab board (or maybe StackOverflow) as it seems to be unrelated to PyTorch and you might thus get better and faster support there.
