We suggest the wording in your contracts is updated to reflect these new changes.
As at the time of writing, Microsoft has not issued any contractual documents effecting these changes (and so there is no specific wording to be flowed down into your own customer contracts).
On this basis, these suggestions are subject to change, and you should be mindful of any commitments you have made to your own suppliers if you are purchasing subscriptions for your customers on an indirect basis.
