Open the Desktop Signal app, connect it to your phone, and watch it download all the supposedly "expired" messages.
They will not always be shown, but they are downloaded.
I don't know about Sky ECC, but Signal requires a Phone # to register, as far as I remember. It's increasingly hard to get anonymous Phone # in the EU. That might be an argument against using it.
