Custom script run with sudo - command not found

Problem:

Ruing a script as sudo retus

sudo: mount-remove-hiberfile: command not found

Info:

cybex@cybex-W55xEU:~$ echo $PATH //and 'sudo echo $PATH' retu the same path

/home/cybex/.rbenv/plugins/ruby-build/bin:/home/cybex/.rbenv/shims:/home/cybex/.rbenv/bin:/home/cybex/.rbenv/plugins/ruby-build/bin:/home/cybex/.rbenv/shims:/home/cybex/.rbenv/bin:/home/cybex/bin:/scripts:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/scripts:/snap/bin

root@cybex-W55xEU:/home/cybex# echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/scripts

The script 'mount-remove-hiberfile' caot be run as a normal user, thus I would need to run sudo mount-remove-hiberfile.

Why does sudo not detect this script?

note: I have found a few questions regarding this but none which answered my question
