### Description

We present the first preliminary results on direct and elliptic flow of particles with strange content ($K^0_s$ and $K^+$) in Au+Au collisions at $1.23\,\mathrm{A GeV}$ measured with HADES. The study of strange particle flow in heavy-ion collision is according to the theory sensitive to in-medium hadron modifications. Kaon flow was seldom measured at such low center-of-mass energy region $\sqrt{s_{NN}} = 2.42\,\mathrm{GeV}$ due to sub-threshold production of strangeness. Thanks to the quantity of $2.6$ bilion events of the $40\,\%$ most central collisions this study is now possible. The obtained flow parameters are compared with previously published world data as well as with flow of non-strange particles. The agreement of measurement with simulations using several transport codes is also checked.
