How to assign custom folder name in google drive integration

I also set up a Google Drive authentication, don't think I got that question of how to name the folders, any way I can change it after it's set up? If I click on Google Drive integration, it only tells me integration is up and running.

I was able to see what you meant. If the Google drive integration was already setup, there is no option to edit the assigned folder anymore. 

To resolve this, remove first the existing integration.

And just redo the integration process. You will be able to see the Create folder option again.

Let us know if still not resolve.

Thanks.
