Azure AD - plugin won’t be supported by Microsoft as of February 29, 2024 what it means?

In Azure AD plugin: Azure AD is info:
" Important : This plug-in is maintained by the Jenkins community and won’t be supported by Microsoft as of February 29, 2024."
What it means?
I have a dilemma whether to install.
I wonder if the plugin will have support after this time and if microsoft, for example, will not terminate services?
