  Evolutionary models suggest that the initial growth phases of active galactic
nuclei (AGN) are dust-enshrouded, and characterised by jet/wind outflows that
should gradually clear the interstellar medium (ISM) in the host by heating
and/or expelling the surrounding gas. eFEDSJ091157.4$+$014327 (z$\sim$0.6) was
selected from X-ray samples for its characteristics that are similar to sources
with outflows which include red, obscured and X-ray luminous. We aim to explore
the environment around this red quasar and characterise kinematics within the
system. We used spatially resolved spectroscopic data from Multi Unit
Spectroscopic Explorer (MUSE) with an average seeing of 0.6" to construct flux,
velocity and velocity dispersions maps. We found that the quasar is embedded in
an interacting and merging system with three other galaxies $\sim$ 50 kpc from
its nucleus. Spatially resolved kinematics reveal that the quasar has extended
ionised outflows of up to 9.2 kpc with positive and negative velocities up to
1000 km s$^{-1}$ and -1200 km s$^{-1}$, respectively. The velocity dispersion
(W$_{80}$) ranges from 600-1800 km s$^{-1}$. We associate the presence of
turbulent and high-velocity components with the outflow. The total mass outflow
rate is estimated to be $\sim$ 10 M$_{\odot}$ yr$^{-1}$ and kinetic power of
2x10$^{42}$ erg s$^{-1}$. The kinetic coupling efficiencies range from
0.01%-0.03% and the momentum boosts are $\sim$ 0.2. These low values indicate
that the ionised outflow is not energetically relevant. These values don't
align with the theoretical predictions of both radiation-pressure-driven
outflows and energy-conserving mechanisms. However, note that our results are
based only on the ionised phase while theoretical predictions are multiphase.
Moreover, the mass loading factor of $\sim$ 5 is an indication that these
outflows are more likely AGN-driven than star formation-driven.
