What happended?

I am trying to access a method for registering a customComponent that is meant to be shown in the page the plugin makes. The method takes an id, name and the react component. i works fine when i use it from the plugin but when i try to access it from the main medusa application it keeps not recognizing the method, but i can se in .yalc that the plugin with the method is in the dependencies.

Expected behavior

Able to access the method and call it.

Actual behavior

Keeps giving me this error or saying it can't find the module:
Could not find a declaration file for module 'report-plugin/admin'. 'c:/Users/****/Desktop/Medus Projects/my-medusa-store/node_modules/report-plugin/.medusa/server/src/admin/index.js' implicitly has an 'any' type.
Try npm i --save-dev @types/report-plugin if it exists or add a new declaration (.d.ts) file containing declare module 'report-plugin/admin';ts(7016)
