The supported chat message content types. Supported types are <code>text/plain</code>, <code>text/markdown</code>, <code>application/json</code>, <code>application/vnd.amazonaws.connect.message.interactive</code>, and
<code>application/vnd.amazonaws.connect.message.interactive.response</code>.
</p>
<p>
Content types must always contain <code>text/plain</code>. You can then put any other supported type in the list.
For example, all the following lists are valid because they contain <code>text/plain</code>:
<code>[text/plain, text/markdown, application/json]</code>, <code>[text/markdown, text/plain]</code>,
<code>[text/plain, application/json, application/vnd.amazonaws.connect.message.interactive.response]</code>.
