I ran into this problem too. I don't think there's a desktop version that you could just leave online 24/7. But I think there's some client (phoenixd? Not sure) that gives you a "phoenix wallet" that you can run.
The other option is to run CLN on start9/umbrel and open a few channels.
Yes , put phoenixd 24/7 on a server, it is very easy to install

Does phoenixd support the creation of BOLT12 offers given a custom input?
Because I can't find that functionality on Phoenix.

Not yet

Being online is not the problem as it supports Google Play Services for the payment while the app is offline.
CLN works fine, but I am curious to check this new feature of Phoenix, which seems to be 99% there.
I'm only missing the ability to copy the BOLT12 offer based on a custom input, which is possible to do in CLN, but I haven't found a way to do in Phoenix.
