Salesforce webform mapping sends taxonomy entity ID (tid) instead of label

Problem/Motivation

In webform, we're using a "TERM SELECT" element to draw select options from taxonomy.

When we map this in -->

/admin/structure/salesforce/mappings/manage/_mapping_name_/fields

And then submit the webform, the TERM ID (a number) not the NAME of the Term gets submitted.

How can I send the term name? instead of the ID?
