The minister said that they have a gadget that works across long distances to send signals.
Of course, not as far as the distances between chaos realms; that function was reserved for the ships. Even then, what the demons had was very outdated compared to human technology.
However, the envoys they sent are equipped with something that could summon their ships to their location, provided that they're not a chaos realm apart from it.
The minister had every reason to believe that the envoys had been devoured even before getting their message because up until now, the ship they used is still active.
This gadget that the envoys had should've been used to summon the ship to their aid once they found themselves cornered. If, somehow, the envoys offended the Bug Empress with their audacity, they should have enough time to activate this emergency signal to get the ship to rescue them.
Whether they could or couldn't is another matter, of course.
