Import an SF Object to GGMAP

## Reproducible Example
Hi, I was wondering if there was anyway to import an SF object to ggmap. I followed this excellent vignette (https://www.dante-project.org/vignettes/geo-unref), but the data I am working with has several scales (cities in counites), and I would like to jitter repeat observations within a specific bounding geometry, and maybe join by fips to a tidygraph object. It was great to be able to use the tidygraph object in the ggmap package, but only having a tile layer limited some options. Did I miss something obvious? Grateful as always to this community.
