JS errors when using cheetah outside Shiny

[DivadNojnarg]

Some piece of code need to be isolated. For instance, this can only work in a Shiny context, if HTMLWidgets.shinyMode === true:

grid.listen(
            CLICK_CELL, (...args) => {
              Shiny.setInputValue(`${id}_click_cell`, args);
            }
          );
