Hello I started very recently with visualforce. The map must show 3 addresses (one for each field) and also to be able to center them when clicking

What should you call the geolocation system?

From already thank you very much
 

Hello I would need to know how to make it send an amil automatically one hour before the date / time field says for example if it is 12:25 I send it at 11:25

I need to carry out a process to send a reminder email when a date / time field is missing an hour from what the record says some would help me

I need to add a button to add more in the window to add more data to users (in this case certifications) but I can't find how to add it
