Square brackets in email confirmation

Remove square brackets from checkbox values in ChronoForms email confirmations.

Overview

The issue occurs when using the standard {data:field_name} placeholder for checkbox fields, which outputs the selected values as an array including square brackets.
Replace the placeholder with {data.join:field_name} in your email template to display only the selected text values without brackets.

I have a checkbox field in my form. It is working fine, but the choice is shown with square brackets in the e-mail.

Is there a way to avoid the square brackets and only show the text?

Using this in the field in the e-mail: {data:begynder_workshop}
