Are LHCb exotics $T_{c\bar{s}0}(2900{)}^0$, $T_{c\bar{s}0}(2900{)}^{++}$ and ${\overline{X}}_0(2900)$ members of an $S{U}_F(3)$ $6$-plet?

Manifestly exotic scalar resonance $X_0(2900{)}^0$ with minimal quark content of $[\bar{c}\bar{s}ud]$ was reported by LHCb in 2020. More recently LHCb reported discovery of manife…
