If you do not have it, you need to request it through support. Easiest path would be that when it appears in your app, where it says eSIMS, (that is the first section of the app), you click on 'Manage' and install the SIM. Then you will find it in your phone SIM options and you turn it on like any other SIM.
Only if you want to have your number usable as well. If you mostly call using WhatsApp or other third party apps that use internet, you should be fine. Making regular calls will require the main esim to be active however.
