Quectel ( @Jason ) / @demabg , right the PDF you mention is at URL https://forums.quectel.com/uploads/short-url/hQDPVOqtTwgWqjvyyrWEtS1y1Q4.pdf .
Indeed it says to install e-SIM profiles you need to use Quectel’s separate program quectel_lpad .
Is there any rationale for this, indeed why did the AT commands not work, @demabg was it clear to you why those AT commands did not work or were not supposed to work, or did you experience a bug and with a later firmware version they started working later?
Asked further about e-SIM functionality on this thread Which Quectel modems have eSIM functionality? Do Quectel models have different levels of e-SIM support? How use e-SIM? .
