Features addition in existing Android firebase project.

We already have a working app (https://play.google.com/store/apps/details?id=com.bellme.io&hl=en_US) but now we want to add some new features to it in our existing code base.

UI designs are ready, we need UI development and integration only**

# Features to add:

1. Rearrangement of Permission page (which is already there in-app)

2. Sent/scheduled reminder reports for the sender: Send, schedule, Rejected, marked completed

3. Comment section for discussion within scheduled reminders for event participants

4. attach multiple documents, images, and App in the reminder

5. Sending push notification 10 minutes before every reminder with our personalize tone & instantly on Poke to participants

6. MSG 91 integration for OTP verification (replacing Google OTP)

7. WhatsApp like 'Invite' sending button in every user selection/adding list who are not on the app

8. Ask to Select at least 4 favorite users & send Automated WhatsApp messages to selected favorite contacts

9. Gifting scroll in Birthday and anniversary reminders

If you have any doubt and need more information to understand we would like to connect and explain further in detail.
