Help setting up a public Ease Type variable in LeanTween

I’m trying to set a public Ease Type variable in LeanTween so I can choose Ease Types from the Inspector

With iTween I just do it like this

public iTween.EaseType easeType;

not sure how to do this with LeanTween

public + LeanTweenType + variableNameHere;

e.g.

public LeanTweenType easeType;
