How To Push Notification When Click Button inside App For All Users

hello every one , can anyone help me, I want to use a push notification that appears to all users when I click on the button. I have tried more than one method and no notification appears - Is this a version with errors that does not send Onesignal notifications from within the admin app ??! I searched the community and nothing worked for me so far Iโ€™m sure the app is connected to OneSignal and sends notifications
