Or if you prefer plotly:
world.map <- maps::map("world", plot = FALSE, fill = TRUE)
p <- sf:: st_as_sf(world.map, coords = c('x', 'y'))
plotly::ggplotly(
ggplot2::ggplot(data = p) + ggplot2::geom_sf()
)

see https://r-spatial.github.io/mapview/index.html The main thing is the data types that map view supports, so you must have a raster or an spatial object like an "sf" object. So points would have to also be an sf object and the two combined (sf has commands to do this) or perhaps you can do ti directly in mapview, I haven't played with it much. The plotly example I sent works with ggplot2, so if you know how to build up the map in ggplot2 you can try that, though again as far as I can see plotly for maps needs sf objects. Mainly sent you the links to get you started. I haven't played with either much, just know that they exist and zoom maps.
