How to setup a revenuecat with Google & Apple's in app purchase plan?

Before we understand the process of setup the plans with revenuecat we need to understand the below concepts.

Entitlements:
- Entitlements is a level of access in a simple manner.
- Level of access refers the no of subscription plan that your app has.
- For e.g. Silver plan has access of 1 module, Gold plan has access of 4 module in the app & Platinum plan has Full Access of app.
- This is just an example you can have different name & business logic.
Products:
- Product is thing that users actually buy.
- Product is an individuall SKU (Store Keeping Unit) which are added in the stores such as App Store, Google Play Store, Amazon Store,Stripe.
- For e.g Product can be Gold Plan Monthly, Gold Plan Yearly. This plan is under the Gold Plan Entitlements.
- Gold Plan Monthly & Gold Plan Yearly are different Product with same entitlement (Level of access).
- Same goes to silver & platinum plans.
- Product is an actual unit that is sold to user.
- Products are attached to the entitlements. - Remember this point
Offering:
- Offering is a group of product that we are offering to the users.
- For e.g. we make a yearly offering that consists of products that has period of 1 year.
- This is optional thing.
