How to publish links to the "Vkontakte" community through the browser's context menu or through the "Share" button on sites?

Question

In contact with

Yesterday I was flipping through Inoreader, on one of the articles I pressed the button on the toolbar with the VK icon to share the link in the community that I lead. However, I did not find such a function. It is noteworthy that the same Facebook, no matter how you scold it, provides more functionality for the regular “Share” button: you can publish a link not only to the page for yourself (FB calls this Chronicle) or send a message to someone, but also publish a link in a friend's Timeline, in a group, or in a "page you manage" . Actually, the last one is not enough for me. VK technical support answered me that there are no plans to expand the API for share buttons yet.
I decided to install the SmmBox extension, but it does not pick up links and does not appear in the browser context menu (I have Opera 35). Try other heaped harvesters for the sake of the simplest opportunity, and are there any that are available via RMB via the link?

If you want to make it so that a person passing by on your site can click the "Share" button and repost the link to your community, then you will not be able to implement this. But if a user logs in to your site through his VK account with the rights to access his communities, then in a simple way you can implement this yourself. You can even replicate the functionality of Facebook, giving you the choice between reposting to your wall, to a group, or to a friend's PM. However, the user may become suspicious when he sees that the VK application associated with your site is asking him to access his communities, wall and private messages.
About the context menu. As far as I know, so far (and not the fact that there will be in the future) browsers do not allow site developers to make any changes to the context menu. The only way to affect the context menu is to create a browser extension and ask the user to install it. But all this, of course, will not cancel the fuss that I described above.
But if you need to export links to your VK group for personal use, then I suggest you read the documentation for the extensions for your browser. Writing your own link exporter through the context menu is not a very difficult task, especially if you have basic knowledge of JavaScript and the VK API.
