same as the precedent mail, don't know if it's what you are requesting but maybe you can look at "consolehelper".
You place your binary in /usr/sbin and link to it in /usr/bin with consolehelper to have a graphical prompt for the root password upon execution.
For example (bat from bacula package):
[slaanesh@3zpc0560 ~]$ ls -al /usr/bin/bat /usr/sbin/bat
lrwxrwxrwx. 1 root root 13 5 dic 15.18 /usr/bin/bat -> consolehelper
-rwxr-xr-x. 1 root root 1376520 5 dic 15.13 /usr/sbin/bat
[slaanesh@3zpc0560 ~]$ cat /etc/security/console.apps/bat
USER=root
PROGRAM=/usr/sbin/bat
SESSION=true
FALLBACK=true
[slaanesh@3zpc0560 ~]$ cat /etc/pam.d/bat
#%PAM-1.0
auth sufficient pam_rootok.so
auth sufficient pam_timestamp.so
auth include system-auth
session optional pam_xauth.so
session optional pam_timestamp.so
account required pam_permit.so

Hi,
I'm not sure this is the answer you are looking for, but, _if_ you
require "root" permissions for your application to work, one of the
possible was would be to use one of the existing wrappers to start your
application from the .desktop file. I'm not sure which one is used by
Fedora, but I was a bit fond of 'xdg-su' in another distribution I
regularly use. To use with xdg-su (a part of xdg-utils ??) would be
something like (in the desktop file):
Exec: xdg-su -c "/usr/bin/app"
This would ask the user for root password when launching the
application. Though I suspect you are looking for something else.
