MYSQL - How to get row count for each day for the last 7 days and include days that don't exist in table

I want to construct a query that returns a count of unique rows per day for the last 7 days, and days that are not in the table should then be filled in with a zero count

Example Data

| PK |   smsMessage   |       t_stamp       |
+----+----------------+---------------------+
| 0  | 'Alarm active' | 2022-09-19 22:23:56 |
| 1  | 'Alarm active' | 2022-09-19 22:23:41 |
