How I can call a Report menu with script?

Hi guys. I want to make replacement for PlayerList. Almost everything is done, and I’m doing friending, blocking actions, and etc.
But PlayerList also has Report User functionality. How I can recreate it (show the following core gui?)

To my understanding, this isn’t currently possible.

It's impossible to support reporting functionality on a custom leaderboard

As a Roblox developer, it is currently impossible to let a player report another player through a custom leaderboard. This is because there is currently no publicly accessible report API. If this was added, I would be able to bring my custom leaderboard closer to feature parity with the built-in leaderboard.
