Mysql2 API Support

[billstron]

I love the idea of this package. We have been searching for the optimal way to handle Aurora MySQL failovers using Sequelize. This package is described as a wrapper, and I would have expected it to expose an API identical to mysql2, but I cannot figure out how to do that without exposing targetClient.client to my application. Is that the correct way to use this package, or is there something else that I'm missing?
