How can I invoke copilot.microsoft.com programmatically via an API so that i can send a prompt in via code or a link?

I would like to submit prompts to copilot.microsoft.com programmatically via API or link such that the user is not forced into the copilot interface to enter a prompt. The problem is to be able to have the user make a preselection from a menu and have that preselection send the complete prompt to copilot behind the scenes so that the user does not require knowledge or repeated entry of the prpmpt directives.
