Addendum to "Super-GCA from $\mathcal{N}=(2,2)$ super-Virasoro":   Super-GCA connection with tensionless strings
  In this addendum, we consider the connection between certain $2d$ super-GCA, obtained from the parametric contractions of $2d$ SCFTs, which can describe the constraint algebra of null spinning strings.
