merged two app codes now facing a problem of permissions fetch.

hello i've been trying to develop my project, and now im facing the current problem, i have one app wich has almost everything i need done. then i learned how to make a permissions and roles management app. now what im almost done doing is merging the two apps, so the app that has the roles management etc i found here https://dev.to/codeanddeploy/laravel-8-user-roles-and-permissions-step-by-step-tutorial-1dij and in its previous tutorial. now that i've put everything of the other app inside this roles management one i see one problem wich is in role assignment page, it's only fetching the roles management program and it's not fetching the permissions from the other pages. my question is where to find or what to replace the permissions, so i can assign roles to the creation or edits of my old app. its main difference from the other it's that it has a folder called admin, and the rest its one folder up , its not inside that folder. (the roles management app)
