Disabled users in Azure AD still has got license in Zoom.

Hello, I have configured SSO. Here is a group on Azure AD which is called: Zoom Licensed Users. I assigned the Licensed role on on it. When I am adding the user in this group, it is automatically getting license in Zoom (If we have free seats). But when I am disabling user from AD, it is removed from the group automatically, but the licence in Zoom is still active. How could I resolve this issue?
