How far is possible to tweak link preview?

[Problem/Question]
About link preview:

  1. is it possible to customize the default picture (content of “sendbird-og-message-item-body__og-thumbnail__place-holder”) in case preview image is not available/broken?
  2. is it possible to change the preview in client? Because Sendbird generate preview as unauthenticated user (we post some messages using straight Sendbird’s API) so inside the app we would like to replace it by a custom thumbnail?
  3. is it possible to decide if to disable the thumbnail per message? Right now seems only a global feature for all or none messages
