By exploiting the Doppler shift attenuation method, the lifetimes of the $2_2^+$ and $3_1^+$ states were firmly established. From the $\gamma$-ray branching and $E2/M1$ mixing ratios for transitions deexciting the $2_2^+$ and $3_1^+$ states, the $B(E2)$ and $B(M1)$ were determined. Various chiral effective field theory Hamiltonians, describing the nuclear properties beyond ground states, along with a standard USDB interaction, were compared with the experimentally obtained data. Such a comparison for a large set of $\gamma$-ray transition probabilities with the valence space in medium similarity renormalization group ab initio calculations was performed for the first time in a nucleus far from stability. It was shown that the ab initio approaches using chiral effective field theory forces are challenged by detailed high-precision spectroscopic properties of nuclei. The reduced transition probabilities were found to be a very constraining test of the performance of the ab initio models.
