How can I search in a map both informations from my dataframe and the OSM address/city

Hello
I’m looking for a solution to search in a map informations from my dataframe, while retaining the possibilité of looking for elements of OSM (like cities, addresses). For example, I would like to search Establishmenets (column=Etab) from my dataframe.

I know only how to search cities/addresses with the AddSearchOSM options
(leaflet.extras::addSearchOSM(options=searchOptions(collapsed=TRUE))

I think we can search informations from my dataframe with addSearchFeatures

But I don't know how to do both.

Unless we need 2 distinct search box in the map.

Thank you for your help
