How do I change a model to detect synonyms too?

Hi, I have been working on a project. So, the base of the project was already built using SpaCy but I want to make the model detect synonyms too.

Example:

Training sentence- “An amount of 150$ should be paid “

Testing data or sentence given in production - “ A *penalty* of 200$ will be charged“

Now, the model is trained to identify the amount 150 using keyword ‘amount’ but I want it to be able to find the number …
