AttributeError: 'SolutionCategoryAPI' object has no attribute 'list_categories_translated'

[sglebs]

I have been using this for ages:

freshdesk_api.solutions.categories.list_categories()

But today I tried this:

freshdesk_api.solutions.categories.list_categories_translated("pt")

but got this:

AttributeError: 'SolutionCategoryAPI' object has no attribute 'list_categories_translated'

Is the documentation wrong? How can I see the APIs really supported?
