hook_help function missing in .module file

Created MR for the issue.
Please review.
Thanks

Hi

I got an WSOD error after applying MR !1 hence I updated line 21 of .module file to fix it this is the error https://monosnap.com/file/1mSqbZkGJYxOjv0dJM0dLr311xV4yG , and this is after I update line 21 https://monosnap.com/file/FoQ6IJvYtft3VCTgItbTeXJjX3fyED

Verified MR1, the hook_help is added for the module. RTBC++
