Is there a way to write text with emoji to Excel or Google Sheets?

Is there a way to write text with emoji to Excel or Google Sheets? I have a dataframe like this, and I've tried write.csv() with the fileEncoding parameter set, but no luck.

df <- data.frame(number = c(1, 2),
                textEmoji = c("Test 👇",
                              "Test 😊"))

write.csv(df, file="df.csv", row.names = FALSE, fileEncoding = "UTF-8")
