reverse geocodoing with tidygeocoder and OSM/Nominatim: How to get results in latin letters/English?

I am reverse geocoding coordinates which pertain to addresses in countries where the Cyrillic alphabet is used. I am using tidygeocoder and OSM/Nominatim as a method. How can I modify my request in tidygeocoder to get the results/addresses not in Cyrillic but in Latin letters/in English?

As far as I can tell, the relevant property in the Nominatim/OSM API is accept-language (see here and here). But adding it to a tidygeocoder request seems not to work.

library(tidygeocoder)
library(tidyverse)

df_res <- tibble(
  lat=41.992073,
  long=21.429506
) %>% 
  reverse_geocode(.,
                  lat=lat,
                  long=long,
                  address="address",
                  method="osm") 

The resulting address reads as

Шпаркасе, Македонија, Водно, Центар, Скопје, Општина Центар, Град Скопје, Скопски СР, 1111, Северна Македонија

Modifying the request to (as suggested here):

tibble(
  lat=41.992073,
  long=21.429506
) %>% 
  reverse_geocode(.,
                  lat=lat,
                  long=long,
                  address="address",
                  method="osm",
                  api_options = list(osm_accept_language="en")
  ) 

leads to an error:

Error: Invalid parameter "osm_accept_language" used in the api_options argument. See ?reverse_geo

Any help? The error also occurs when using "osm_accept-language". Many thanks!

Thanks to a reply from the package author on github I found the answer:

df_res <- tibble(
  lat=41.992073,
  long=21.429506
) %>% 
  reverse_geocode(.,
                  lat=lat,
                  long=long,
                  address="address",
                  method="osm",
                  custom_query  = list("accept-language"="en-US"))
