This module lets you make use of form modes for default entities as nodes, taxonomy terms or comments. It hooks up form modes corresponding to entity form routes. The route to add or edit an entity is called "entity.taxonomy_term.add" or "entity.node.edit_form". All you have to do to display i.e. the edit form in its own form mode is to offer a form mode with the (machine) name "edit_form" (the last part of the route name). This is automatically selected by this module to display the form.
