How to assign user rights for custom developed plugin ?

Hello, Thank you in advance,

I have developed one custom plugin as per my requirement, and I have also added 3 user role group from the backend, now i am able to manage default built-in Shopware backend menus under roles & permission, but I am unable to hide my own custom plugin, what to do for that ?, I also checked https://docs.shopware.com/en/shopware-5-en/tutorials-and-faq/user-rights-for-plugins-without-acl-support, but no output I am getting from this link…
