Holding SceneManager.LoadSceneAsync until a button has been pressed?

Hey guys,

Im having trouble trying to figure out how to transition from a loading scene to my main scene after the press of a button. Right now i have a loading scene which contains a minigame. During this minigame, my next scene is called in the SceneManager.LoadSceneAsync function in the background. Is there anyway to process the function but hold the scene transition until a button is pressed? Thanks any advice is much appreciated :)
