Explanation:

Modal auxiliaries are helping verbs used in sentences. Some examples of modal auxiliaries are should, could, can, might.

• The modal auxiliary 'can' is used to show possibility. This auxiliary is generally used to give orders.
• Similarly 'may' is used to show an unsure future, or even used to ask for permissions or requests.
• The above sentence doesn't show any type of order or request.
• There are chances of it being a request so the auxiliary 'may' will be used, however 'can' will also be suitable in case of the sentence being an order.
