We present calculations of dielectron anisotropic flow in heavy-ion collisions at HADES beam energies from a hadronic transport approach. The ongoing experimental analysis employs the traditional reaction plane method to evaluate coefficients $v_n$ and claims see isotropic radiation thermal quark-gluon plasma. show this work, that region above pion mass, dilepton measurement might suffer cancellation effects mask complicated underlying dynamics. Contributions different baryonic mesonic resonances collective behaviour with signs lead an overall vanishing elliptic flow. To differentiate contributions, we propose employ scalar product method, which exploits previously measured create reference planes. As proof concept, calculate $v_2$ dielectrons for Ag+Ag $\sqrt{s_{NN}}=2.55$ $\mathrm{GeV}$ both methods investigate contribution each source, concluding provides proton tagged as two distinct measurements, disentangling various sources.
