Your lease, aka AST (Assured shorthold tenancy) is only for your bedroom.
You are just renting a room from Lyvly, which means you are only responsible for your room.
The shared areas are looked after and managed by Lyvly, which means the housekeeping isn't mentioned in your lease.
If you would like housekeeping in your bedroom, this is an additional paid service.
If this doesn't answer your query, then please get in touch via email@example.com
