We identify the soft current algebra between the graviton, the gravitinos, the vectors, the Majorana fermions, the scalar or the pseudoscalar, from the ${\\cal N}=4$ supersymmetric $w_{1+\\infty}^{2,2}[\\lambda=\\frac{1}{4}]$ algebra, in two dimensions with the ${\\cal N}=4$ supergravity theory with $SO(4)$ global symmetry in four dimensions found by Das (at Stony Brook in 1977), via celestial holography.
