https://github.com/MicrosoftDocs/semantic-kernel-docs/blob/main/semantic-kernel/concepts/prompts/handlebars-prompt-templates.md

The first example is using liquid syntax

        Make sure to reference the customer by name response.
    </message>
    {% for item in history %}
    <message role="{{item.role}}">
        {{item.content}}
    </message>
    {% endfor %}
    """;

the seconde example is correct

        Make sure to reference the customer by name response.
    </message>
    {{#each history}}
    <message role="{{role}}">
        {{content}}
    </message>
    {{/each}}
