  "abstract": "We prove that $\\mathrm{C}^*$-simple groups which admit a faithful extreme boundary are $\\mathrm{C}^*$-selfless. More precisely, we establish complete selflessness of the canonical inclusion of the reduced group $\\mathrm{C}^*$-algebra into the reduced crossed product. In particular, the Higman--Thompson groups and the Brin--Thompson groups are $\\mathrm{C}^*$-selfless.",
