The minimum quark content of this 3-body bound state is $cc\\bar{q}\\bar{s}$ with $q=u,d$. It will be an explicitly exotic tetraquark state once discovered. In order to confirm the phenomenological study of the $DDK$ system, we can refer to lattice QCD as a powerful theoretical tool parallel to the experiment measurement.
