display the number of products added to the quote in the menu header

Very good morning, I am working on a client’s website and he requires that the client be able to see a type of drop-down list of the items that he has quoted or that, finally, it allows him to see a number or quantity of products added to the quote without You have to go to the page of quoted products every time.

I have seen that for other Astra themes there are scripts that you indicate must be added to the function.php of the child theme.

The theme of the website is woodmart and we are working with visualcomposer as a visual layout designer. Is there any code or script that adds this functionality to woodmart. If it could be done, you could use a code snippet, instead of adding the code directly to the function.php

I would appreciate if you could tell me how to perform this task.

Thank you so much
