How do I open OrbitNote in Google Docs?

Could you please clarify the steps required to open OrbitNote within Google Docs? I'm interested in understanding the process as I'm not familiar with OrbitNote being integrated directly into Google's document platform. Are there any specific plugins or extensions that need to be installed? Additionally, are there any limitations or considerations I should be aware of when using OrbitNote within Google Docs? I'd appreciate any guidance you can provide to help me navigate this process.
