If there's a
Decathlon near to you could be worth having a look at the Triban bikes, but to be fair anything will be better than the Zelos, it's a starter bike and quite heavy, unfortunately it's not worth spending on upgrades on it as the 7 speed Tourney is a freewheel rather than a cassette,so it would need new wheels, groupset, and the steel fork is very heavy, but expensive to replace with a carbon item, it'll be cheaper to sell it while prices are through the roof and put the money to a better spec bike.
