1  From an amplitude analysis of the decay ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}_S^0}$ with a significance of 4.0 $\sigma $. The mass difference with respect to the charged partner in AAIJ 2021E is $-12$ ${}^{+11}_{-10}{}^{+6}_{-4}$ MeV.
2  Pole mass for a mass-, width-dependent Breit-Wigner fit to the mass spectrum recoiling against ${{\mathit K}_S^0}$ at center of mass energies between 4.628 and 4.699 GeV, with a significance of 4.6 $\sigma $.
3  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 15 $\sigma $.
4  Pole mass for a mass-dependent Breit-Wigner fit to the mass spectrum recoiling against ${{\mathit K}^{+}}$ at center of mass energies between 4.628 and 4.698 GeV, with a significance of 5.3 $\sigma $.
