Get labels of all the fields available for a module

Hello,

I have a requirement where I need to get the list of all fields available for a module. I am currently using this endpoint to get the data:

/rest/v11/metadata?type_filter=modules&module_filter=Contacts

Everything is working fine with this except the label. The response doesn't have anything that can be shown as a label for the user on our side.

'First Name' instead of 'first_name'.

Is there anything that can be done for this?

I have attached the response format I am getting.
