How to auto show Google Map Marker Info Window?

Annotation%202019-11-12%20004255

I have tried the following steps on map ready without success:

map.maps1.goToMarker(output_location.data.query_location[0].event_location_id);map.maps1.bounceMarker(output_location.data.query_location[0].event_location_id);map.maps1.showInfo(output_location.data.query_location[0].event_location_id)

Demo site: http://d3mo.esy.es/map

Note: Routing is enabled on the page and map is located within content page.

Anything that I’ve missed? Let me know the proper steps to achieve it. Thanks.
