Add VK account support

Hi team,

I’d like to request support for VK accounts.

We’re currently adapting Letwiz for our team and integrating it with the Zernio API. So far, the product has been great to work with, and VK support is the main missing piece for our workflow.

VK is one of our key platforms, so adding it would help us manage all our channels in one place and make adoption much easier for our team.

Would love to see this considered for the roadmap. Thank you!
