I tried with the following method but I am not sure why I am seeing ‘en_US’ .
Also I want to add any icon as no icon is visible for custom notifications
Notification.create!(
notification_type: 14,
user_id: 82226,
topic_id: 82269,
post_number: nil,
high_priority: true,
data: {
message: 'Your last was removed due to spam content',
display_username: 'Post deleted',
topic_title: 'Post Rejected'
}.to_json
)
