Best Approach for Implementing Custom Methods in Laravel Nova

We are currently working on a Laravel project integrated with Laravel Nova. Throughout our development, we have encountered several scenarios where we need to implement custom methods/functions similar to how we do it in Laravel.

While researching possible solutions, I came across some options such as using Parent::boot method. However, I'm unsure about the best approach to take for our specific use case. Here are some options I've considered:

1 Using Parent::boot Method: How can I effectively use the Parent::boot method in Laravel Nova to implement custom methods for our Nova resources?

2 Utilizing Helper Functions: I'm considering using helper functions to encapsulate reusable logic. What would be the best way to create and call these helper functions within Laravel Nova resources?

3 Creating Abstract Class: Would it be a good idea to create an abstract class for our Nova resources to share common logic? If so, how can I implement and utilize it efficiently?

4 CRUD Operations with Resources: I've heard about using CRUD operations with resources. How can I leverage this approach to implement custom methods effectively?

I'd appreciate any insights or advice on which approach would be best suited for our project and any examples demonstrating their implementation. Additionally, if there are any other approaches that I might have missed, I'd love to hear about them as well. Thank you!
