Apps can't access internally mounted SSD

So this question has been asked a bunch of times but the discussion goes over my head. I need a step by step guide to fix this issue.

I have an internally mounted SSD. Its formatted to ext4. I have modified the permissions on the disk to have read/write enabled for SUDO.

Contents of my /etc/fstab file are as follows:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=15ff6a59-4964-43fb-8f6f-35106232108a / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda1 during installation
UUID=4C99-DC9A /boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0
