While we may never have a telescope outside of our galaxy so that we can then look in at it, we don't need to do this in order to see the Milky Way galaxy in all of its glory.
This is because of a phenomenon known as gravitational lensing. While we are only generally aware of this occurring in such instances as an Einstein Cross or an Einstein Ring, the reality is that this can occur on a much grander scale. Galaxies that cause Einstein Crosses or Rings are massive, but they are not nearly as massive as the Great Attractor.
In our mapping of the cosmos, we have not accounted for the Great Attractor's gravitational effects on the pathing of light from distant galaxies. Being so massive, its effects are much more drastic than the minimal lensing of a galaxy in an Einstein Cross or Ring. Rather, its effects are immense and influential throughout the entire length of time that light travels from distant galaxies.
And so, because of this, we are able to see optical illusions in the cosmos. One particularly interesting optical illusion is that light from the Milky Way galaxy, traveling at just the right angle (which it necessarily would due to it traveling away at all angles), is theoretically able to be bent back by gravitational lensing so that it arrives back at Earth.

GAMA202627 and its accompanying galaxies are called "Twins" to the Milky Way and our accompanying Large and Small Magellanic Clouds.
"The Milky Way is a fairly typical galaxy on its own, but when paired with its close neighbours – the Magellanic Clouds – it is very rare, and could have been one of a kind, until a survey of our local Universe found another two examples just like us."
As with all mapping of the cosmos, the Great Attractor's gravitational lensing effects have not been accounted for, thus the researchers never considered the possibility that they were actually looking at the Milky Way.
But with consideration of gravitational lensing, it is highly likely, due to their identical nature, that this image is not one of a separate and distinct galaxy but rather one of The Milky Way itself and its neighboring Magellanic Clouds.
