How to integrate embed google map api show nearby place within radius?

Im developing this website Resultados de busca – republicasunicamp.brandinup.me and im trying to integrate google maps into Houses (houses is a custom post type), to show determinated houses in radius of X KM of a univesity, how can i do that?

And the other question, is how can i show the estimated time walking, driving and using a bus between this house and university.

OBS: House and University are 2 different post type created. Im using crocoblock plugins (jet engine, etc, and elementor)

Did you manage this, do you have a bricks solution?
