which graph API I could use to remove specific users from an application in Azure Active Directory?

From @tquangfxvia Twitter:

I have follow the instrustions in the blog you suggested for bulk assign user to application in Azure AD (
edutech.me.uk/administration…)

However, it returns error when running for already assigned users. So I wonder is there anyway to bulk remove user assignment to application in AAD using graph api ?

When I bulk assign user to the application, I use
graph.windows.net{TenantId}/users/{userID}/appRoleAssignments?api-version=1.5

My question is which graph API I could use to remove specific users from an application in Azure Active Directory?

Thanks,
