Adding a Leaflet map 2

Hello, I am trying to add a leaflet map in my website created using the ceevee skeleton. I have downloaded the leaflet and asset plugings and looked at the description given in the plugings themselves and at some earlier posts here in the forum. My problem is that I fail to see where to add the code (using assets plugin and without that pluging). If I want to simply add the map to one of the pages in my modular website, how do I have to do the call to the map? I am kind of new to grav so I am pretty sure the answer is quite straightforward even if I don't see it. Any clue would ge welcome.
