Yes, you can access the internet data from your eSIM on other devices by setting up a personal hotspot.
You can accomplish this on iOS by going to the "Personal Hotspot" option in settings, and on Android by going to the "WiFi hotspot" settings.
How can I determine which eSIM is being used to transmit my data?
On the Android platform:
Navigate to Settings > Network & Internet > Mobile Network to begin.
You'll see the name of the eSIM you created during installation here.
On iOS:
Navigate to Settings > Cellular or Mobile Data.
The word "On" will appear next to the name of the eSIM being used.
On Samsung Electronics:
Navigate to Settings > Connections > SIM Card Manager to begin.
The name of the eSIM in use will appear under preferred SIM card.
