Rclone Can't Update Plex Library from Mounted Google Drive

What is the problem you are having with rclone?

So, I can add a folder from my Gdrive through Plex and get everything added and playing just fine, but I can't seem to update that library once new folders get added.
I have to delete and re-add the folder or something in order to update the library.

I heard that I could use this to assist, but I have no idea how to get it to work on Windows:

I saw info on it from this thread: Plex update new files

Any advice?

(I just added the third show, FLCL to test it today).

Running the latest Rclone version, 1.50.2, with Windows 10 64bit, Using Google Drive.

My rclone command:
rclone mount --dir-cache-time 96h --vfs-cache-max-age 48h --vfs-cache-mode writes --vfs-read-chunk-size 24M --poll-interval 5m --fast-list --vfs-read-chunk-size-limit 1G --buffer-size 2G "Gdrive Rclone:/" X:
