Import S&P data from Mexico with GetSymbols

Question

I am using GetSymbols to import financial data from Yahoo Finance, I understand that the ticket I should use is the one that appears on the Yahoo Finance page next to the name, however, I want to import the data from the S&P Mexico ADR and the ticket that appears is "^BKMXT", but when running it says that the data cannot be imported. Is there something I'm doing wrong? Or should I use another ticket to be able to work with this data?

I am using the following code in R in Google Colab[1]:

getSymbols("^BKCMX", src = "yahoo", from = "2020-01-01", to = "2020-01-30", periodicity = "monthly")
