Want to allow application to mount a drive using rhel 8

The mount(8) man page explains what to do.

   Non-superuser mounts
       Normally,  only  the  superuser  can  mount filesystems.  However, when
       fstab contains the user option on a line, anybody can mount the  corre‐
       sponding filesystem.

       Thus, given a line

              /dev/cdrom  /cd  iso9660  ro,user,noauto,unhide

       any  user  can  mount the iso9660 filesystem found on an inserted CDROM
       using the command:

              mount /cd

       Note that mount is very strict about non-root users and all paths spec‐
       ified  on  command line are verified before fstab is parsed or a helper
       program is executed. It's strongly recommended to use  a  valid  mount‐
       point to specify filesystem, otherwise mount may fail. For example it's
       a bad idea to use NFS or CIFS source on command line.

(Bad idea it may be, but it works if you have the mount command syntax correct, and that's quite easy.)

       For more details, see fstab(5).  Only the user that mounted a  filesys‐
       tem  can  unmount  it again.  If any user should be able to unmount it,
       then use users instead of user in the fstab line.  The owner option  is
       similar  to the user option, with the restriction that the user must be
       the owner of the special file.  This may be useful e.g. for /dev/fd  if
       a  login script makes the console user owner of this device.  The group
       option is similar, with the restriction that the user must be a  member
       of the group of the special file.
