We are informing you again of the format corresponding to one patient information.

______________________________________________

command : beforedelete or beforehidden

..

content : '202' --> whatever you want to delete or hide before all

If you enter the ID value as '202' in the content, all of the previous ID rows will be deleted or hidden from each app user's phone.

______________________________________________

 

______________________________________________

command : deleteone or hiddenone

..

content : '211' --> whatever id that you want to delete or hide

If you enter the ID value as '211' in the content, the id's one row will be delete or hidden from each app user's phone.

______________________________________________

command : bfdatedelete or bfdatehidden

..

content : '2020-05-01 15:03:33' --> whatever date that you want to delete or hide before date all

If you enter the date value as '2020-05-01 15:03:33' in the content, all of the previous date rows will be delete or hidden from each app user's phone.
