Error opening directory '/media/sf_C_DRIVE': Permission denied

I tried to share a folder from Windows 10 host to Kali 2020.1 Linux guest using VirtualBox but I am getting the following error message:

Error opening directory '/media/sf_C_DRIVE': Permission denied

To fix, do:
$: sudo adduser $USER vboxsf
Then log-off then log back in. If this does not work, reboot the VM

Getting similar issue using Fedora 33 on VirtualBox 7.0.12 (tested up to Fedora 41 [VBox 7.2.4]) , below is the error message
This location could not be displayed You do not have the permissions necessary to view the contents of "sf_D_DRIVE"
To fix do the following and reboot the VM.
$: sudo usermod -a -G vboxsf $USER
