  "abstract": "We prove that the reduced crossed product $C^*$-algebras of almost periodic actions of countable discrete groups having a topologically free extreme boundary on unital, separable, simple, exact, $\\mathcal{Z}$-stable and monotracial $C^*$-algebras are selfless. We combine Ozawa's \"tree-graded'' space method with the theory of strong convergence of indexed families for the proof.",
