Run a plugin as soon as the user click on a conversation

Hello,

I am creating a plugin that will suggest to the user a content to its reply based on the previous messages exchanged by the customer

After some tests, I noticed that, using a plugin

• I am obliged to open the plugin (Sidebar or Composer) to see the draft created with the content suggestion

Now here is what I noticed: User click on a conversation → User open the plugin → the plugin create a draft containing the suggested content

What I want: User click on the conversation → The plugin create a draft containing the suggested content 

Is not possible to run my plugin as soon as the user click on a conversation? Opening the plugin will be to access to additional features

Regards,
