R: How to change country names in Quanteda/Newsmap?

Question

I'm trying to do a tokens_lookup() with the Newsmap package in a 1980s computer mag from Switzerland in german. But countries had other names back then. I need to include the sovjet union, tschechoslovakia etc. Also I need to replace all german "ß" with "ss" (We don't use ß in Switzerland.) How can I change values in a dictionary?

I have tried:

dic <- data_dictionary_newsmap_de
dic$EUROPE$EAST$SU <- c("sowjetunion", "udssr", "moskau")

You can find the original dictionary in the YAML format in Newsmap's repository, so you can edit in a text editor and load using dictionary(file = "xxx.yml").
