Channel package

Hi guys
Im novice in zammad development
And i have only one day to resolve my issue(
I have a real project - to add to zammad a new channel
I tried to do this way - i duplicated all the files with telegram channel and everywhere where word “telegram” appear - i added also connection to my files
For example i added one file in routes folder

I see that somehow my files are used because in cache directory my key word appear

But i cant understand why
a) no item appear in settings-) channels
b) even ifi manually type something like http://HOST/#channels/MYCHANNEL it goes to default settings page instead of my page

Can You say me how to configure route or maybe some channel package code because i dont understand what im doing wrong…
