  ASASSN-20hx, a.k.a AT2020ohl, is an ambiguous nuclear transient (ANT), which
was discovered in the nearby galaxy NGC6297 by the All-Sky Automated Survey for
Supernovae (ASAS-SN). We have investigated the evolution of AT2020ohl using a
multi-wavelength dataset to explain the geometry of the system and the energy
radiated by it between X-ray and radio wavelengths. Our X-ray, UV/optical, and
radio observations of the object jointly clarify the association of AT2020ohl
with the nuclear activity of NGC6297. We detected radio counterpart of
AT2020ohl 111 days and 313 days after the discovery in Jansky Very Large Array
X-band with flux densities 47$\pm$14 $\mu$Jy and 34$\pm$3 $\mu$Jy,
respectively. Using multi-wavelength data analysis, we nullify the possibility
of associating any stellar disruption process with this event. We found some
evidence showing that the host galaxy is a merger remnant, so the possibility
of a binary SMBH system can not be ruled out. The central SMBH has a mass of
$\sim1.2\times10^7$ M$_\odot$. We propose the accretion disk activity as the
origin of AT2020ohl $-$ it is either due to disk accretion event onto the
central SMBH or due to the sudden accretion activity in a preexisting accretion
disk of the system during the interaction of two SMBHs which became
gravitationally bound during a merger process. However, we also admit that with
the existing dataset, it is impossible to say definitively, among these two
probabilities, which one is the origin of this nuclear transient.
