Thanks @ogra for your tips. It seems that I gave a little step further 
… but the snap build failed.
After removing the architectures section from the initial yaml file. I tried to build the snap on snapcraft.io/build. (I tried the snapcraft remote build approach as well, and problems were exactly the same.)
Part of the build log is here:
WARN engine electron-notarize@1.0.0: wanted: {"node":">= 10.0.0"} (current: {"node":"8.10.0","npm":"3.5.2"})
WARN engine asar@3.0.3: wanted: {"node":">=10.12.0"} (current: {"node":"8.10.0","npm":"3.5.2"})

Any tip regarding these error messages? It seems to be related with node version…
I remember that I’m trying to complete an example on a RPi3. So I wasn’t expecting to face these problems.
Thanks
