Dot of numeric keypad as a character of decimal separator in spreadsheet

Hi,

I am trying to configure CODE with Nextcloud and I would need to know if it is possible to configure it so that when I press the Dot of the numeric keypad a decimal comma separator appears in spreadsheet (this is the standard in LibreOffice, because the comma is the decimal separator in Portugal).

The local language configuration is Portuguese in NextCloud and CODE

Thank you
Best regards
