The Reply tool was enabled by default for everybody on Monday, 7 March 2022. See Wikipedia:Village_pump_(proposals)#Offering_the_Reply_Tool_as_an_opt-out_feature.
This script replaces the reply link (currently the dull text — [ Reply ] ) with a better-looking graphic – the Speech balloon emoji — 💬.
The script does not change any actions – just the text displayed for the reply link.
The script probably only works on Vector. I have not tried it on other skins or on Evil Vector.
