On the https://documentation.magnolia-cms.com/display/DOCS62/Magnolia+6+UI+ports+of+5+UI+field+transformer+classes page, "It would be great if there was more info for each provider, sth in line with the one that already exists for CompositeTransformer. i.e. not only that it somehow works with this provider, but also a little detail on how to do it ..."

Ask a developer to provide that information and add it to the cells in the "In 6 UI" columns.
