Translate Widgets with polylang

Hi.

I tried blocksy for an local project (first) and wanted to use it multilangual with the polylang plugin.

Everything works well accept with widgets.
I couldn’t found a way to translate e.g. the contact-widget or other ones.
How can I get that solved in the standard?

Currently I help myself via another plugin, which I came across via this post.

But I hope I can get it working without another plugin.

Thanks for your support.
