// Called when a suggestion is selected. `index` indicates the position of the

// the form activity params from somewhere, so if the client is stateless the
// params need to be set in the `suggestion` itself, otherwise the client needs
// to provide the params by tracking them.

// fill the form, so this version of 'didSelectSuggestion' can be used without
// requiring a separate function call to provide the form activity parameters.
// If the parameters have already been provided by a previous call, then the
// 'didSelectSuggestion' overload above should be used. `index` indicates the
// position of the selected suggestion among the available suggestions.
