I saw this bug (around 2 cm) in the front of the balcony door inside the room.

I googled and found two same insects- Assassin bug and Kissing bug. Could they hide their eggs inside the room? Should I be worried? I live in Vienna, Austria

Thanks in advance

Update: I found this bug here https://www.massaudubon.org/learn/nature-wildlife/insects-arachnids/western-conifer-seed-bugs The bug that I saw looks like a Western Conifer Seed Bugs! Do you agree?

Yes, it does seem to be a Western Conifer Seed Bug (Leptoglossus occidentalis). Not a hazard to people.

Photos from Italian language wikipedia.

This ref below suggests it may be looking for somewhere indoors to wait out the winter. It lays eggs on conifer leaves.
