How to make a Activity Calendar

Troubleshooting

I want to make an activity calendar for my team, and if my teammate has an activity for a specific date, I want to display their profile picture on my calendar on the specific date of their activity. I used the Firebase database on my backend. Can anyone help me with this? thank you in advance

What have you tried so far?

I have already bind the user to the dates of my calendar. But all the dates appeared in the profile picture of my teammate.
