/// <remarks>
/// AI Studio offers such a link as a button, and a click opens it right away. A plugin may therefore
/// only link to a website or to a mail address. Any other scheme would let a plugin open something on
/// the computer of the user, and plain text, which a support contact may be, gets no button at all. The
/// links which the Assistant Builder fills in tell nothing about a plugin and count as not stated.
