Give access to guest with MAM in Intune

Hi,

i'd like to know if it is possible to give acces to our business Apps (MAM compatible) or O365 Apps for various GUEST with their own domain

For example :

My enterprise Tenant use this domain : mailto:example@mywork.com

The GUESTs use this domain : mailto:guest@microsoft.com or mailto:guest@gmail.com

The GUESTs are working for my enterprise, so they will have access to a SharePoint or a developed App with the MAM sdk. We want to manage the access to these Apps with MAM and we'd like the GUESTs to use their own email (différent domain from our enterprise), is it possible ? or the GUESTs must have an account with the domain mywork.com ? (mailto:guest1@mywork.com for example)

thanks
