Hi.
If it's okay, I'd like to give this one a try.
I'll have a look at the codebase and get started as soon as possible. Will ping here if need any guideline. 😅
If you have any pointers for where to get it started with, please let me know.
Also, do implementing these interfaces come with any tests that I need to run to verify?

Sure @selectiveduplicate, I've assigned this to you.

There are no existing tests for the mock implementations. However, you can refer to the mock implementations of other interfaces in recent PRs #1101 and #968 to get an idea of how it can be done. PR #1101 also includes simple tests for the implementation.
