China Airlines question about transfer in Europe

So because of the situation in the middle east my family and I is flying from a different European Union country to AMS to TPE. In AMS we have about 1h30 transfer time. This first leg of the journey is executed by Lufthansa. I assume our luggage will move automatically from the Lufthansa flight to the China Airlines flight.

In case we miss the connecting flight due to a delay in the first part of our journey to AMS, will there be a China Airlines booth somewhere to help us? Or where do we go/call?

Any advice? Since 1h30 looks short.
