Routing over IPsec tunnel through the remote network

Hello Im a beginner in this field, Im currently stuck at this point . i’ve tried everything and the problem still there.

Im using IPSEC IKEV2 Policy Based VPN on Huawei to connect to Mikrotik office.
To connect from Mikrotik Office to client server im using mikrotik via MPLS IP VPN

From Huawei to Office Mikrotik already estabilished , connected tested via ping and vice versa
From Office Mikrotik to Client web server already connected tested via ping and vice versa and web based can be accessed from LAN

The problem is why from Huawei to Client cant be connected, what am i missing ?

Here is the topology
