Aspose.PDF Set Alternative Text

There is a coding example to set alternative text for an image at Set alternative text for Image|Aspose.PDF for .NET but I do not see the TrySetAlternativeText / TryGetAlternativeText methods on the XImage object. Are these methods still available?

@Greg103
These methods were added in the latest version of the library - 25.06.
Are you using this version?
