To monitor the activities that users perform on a homegrown cloud application, you need to create a new cloud application definition using the Chrome extension. The Chrome extension is a tool that allows you to record the traffic and activities of any web-based application and create a custom app definition that can be imported into your Netskope tenant1. This way, you can enable Netskope to detect and analyze the activities of your homegrown cloud application and apply policies accordingly. Therefore, option D is correct and the other options are incorrect. References: Creating a Cloud App Definition - Netskope Knowledge Portal
