I just found the answer to this the other day – super easy!
you can adjust it in your shortcode
eg add this to the shortcode on the page you are displaying connections on
[connections str_bio_show='Learn More' str_bio_hide='Close Learn More' str_bio_head='Member Information']
that will replace the exisiting wording with the words in quotations
that’s how it work with cMap template I assume it’s pretty similar in other templates- full info along with other labels you can change are here
