Yes

Yes to silicon, or adhesive or both

Whatever works but most likely silicone

Something that will stick, but can be removed without damage. Silicone is your best bet. Stay away from adhesives.

Thanks, yes I wanted it to be removable so I was worried about adhesive but was also skeptical silicone would have enough “stick”

I will go with silicone

Silicone. Pretty standard way for most bathroom sinks

I have bitched, moaned and complained while chipping/prying my way through 20-30 year old silicone on more than one occasion.
