On Drupal 8 I installed the "Message" and "Flag" modules.
I created a flag "Report content" and I want a message to be sent to the site administrator as soon as a content is reported.
Messages will be displayed in a table view.
The "Report content" flag includes a "Pattern" field.
The message must contain the date of the flag, the author of the flag, the flagged node and the pattern of the flag.
For the flag no problem, but for the module "Message" it is a discovery.
After creating a message template "Reported Content", what should I do?
I read all the documentation and I can not.
I also installed the mudule "Message notify" and "Message UI".
