It is the principle functionality that we're leveraging, which really can be defined as recordings and playbacks. So, you record the scripts that you want to execute and you also want to be able to playback. So, these are the features that we are largely leveraging. There are flows and scenarios, and they are the design aspects that fit within the playback and the recording solution. For me, they are the core of Qualibrate, and that's what we're using.
