How to activate eSim profile?

I set up my new Mudi 7 and downloaded an eSIM profile via a QR code.
Where can I find the downloaded eSIM profile, and how do I activate it?
I only have one Vodafone eSIM profile. This is probably the default setting when the device is shipped.
When I try to download the profile again, I get a message saying that this profile has already been downloaded and that multiple downloads are not allowed. So it must be somewhere on the Mudi. But where?

For Mudi 7, the esim management has been moved to Cellular section, as shown below.

If an eSIM profile is installed, you can access eSIM management there to view and manage it.
Alternatively, you can also manage it directly on the screen board. Relevant instructions are provided below for your reference.
