Need help with a Visual Studio Code Copilot extension

[pikoscielniak]

Hi,
Could someone help me solve this problem: How can I add custom code completion to GitHub Copilot's editor? Or perhaps someone could suggest how else I could get suggestions in the Copilot chat editor, such as using custom commands with a # like in #file? My problem is how to get custom suggestions in GitHub Copilot's chat editor so that I can add information from some API queries to the prompt.
