Confused about DeviceProfileID

I’m trying to create a device using API, however they’re asking for the deviceProfileId, which I can’t find anywhere.
I tried to used one from a device that I already created, and I had an error message “object already exists”, then I tried to use a random one and it said “Object not existing”

How can I use that api?

In the lora-app-server web UI, it’s the 4th item from the bottom in the left-hand column (assuming you have gateways enabled). You need to define a device profile before you can attach a device.

Oh I see, but I can only set a name for it, how can I see its ID?

Oh I found it, thanks for your time bconway!

Where is it ? I do not find it ):
