Experimental (symbols) K$^\pm$K$^\pm$ invariant radii $R_\mathrm{inv}$ (left) and correlation strengths $\lambda$ (right) shown as a function of the pair transverse momentum $k_{\mathrm T}$ for six multiplicity classes and compared with the EPOS~3 model predictions. The width of the bands represents the statistical uncertainty of the EPOS~3 predictions The different colors of the bands correspond to the respective centralities as given by the ALICE data Statistical (lines) and systematic uncertainties (boxes) are shown for the data points. The points for lower multiplicity classes are slightly shifted with respect to the 0--5\% multiplicity class (black symbols) in the $x$ direction for clarity.
