Samsung Jet Bot AI Robot Vacuum set-up

I bought the above, product code VR50T95735W/EU, and am trying to set it up through the SmartThings app.

I did once get as far as “your product is being registered” with subsequent message abt it not being able to connect with product registration through “poor WI FI connection”.

Then I go through it all again. I come up with this “press the recharging button and hold for 3 seconds” but the only button I see is the on/off rocker button, no such thing as holding for 3 seconds. I certainly do t see a button anywhere near the area in above illustration. My sight isn’t the best, and I have a disability so it’s tough going trying to do it. Has anyone come across this and resolved it or should I be looking for sone other button or virtual button? Can’t see anything relevant on instructions from box.
