Get data from Analysis services data source (live) for external B2B users

Hi,

i added external user to Azure AD, we assign him power bi pro license, i maped the external email in mapping names to internal user, but when i try to get data from analysis datasource external user doesn't see it.   Also whn i open this gest user in Azure licenses tab i don't see any lisence. I have 2 questions. First - if i have to see power bi pro license assigned to this external account in azure database? And second,  If someone can explain why external user can't see analysis services database in this case? Maybe i forget to do someshing else? Thank you very much for your help.
