Solution
As this is an end-to-end product design, these are some of the many features and views that I designed.
During the design research phase, we found almost all the other chatbots service on the market support a single chatbot-sources structure. Thus when businesses had to create multiple chatbots, they had to upload sources to the new chatbot all over again, making it a hassle.
We wanted to solve the problem by introducing the notion of knowledge bases, which is a library that consists of different sources that can be shared across projects/chatbots.

When first designing the knowledge base's main page, I came up with a simple card layout with icons and no. of files to display the knowledge bases, but quickly realized the lack of information might refrain users from quickly identifying between different knowledge bases.
Thus in the next iteration, I added other useful data for clear distinction between the knowledge bases for quicker selection.
Lesson: When designing a B2B product, data and information is key as it helps users make quicker actions and informed decisions.
