Hello,
I would like to know if there's a solution to choose options to display in the Share and Report Widget, as we can see on the screenshot.
That looks like a third party plugin maybe. Or, are you asking for a feature request to add those options to the share widget? I am not sure what you are asking as the report button wouldn't have any social options. Can you please provide more information?
I thought this widget was native in Social Engine, I would like to add other social networks such as Instagram or Tik Tok.
The one you show in your screenshot looks like a third party one maybe. But, we do have AddThis and you set up which social networks show in your AddThis settings at AddThis. Here's a tutorial for how to use AddThis:
