I am looking to make the size of the font bigger in the legend of a chart, I am trying to change it from a topic with a javascript file but I have not managed the change.

I have inserted this script:

options: {
    legend: {
        display: true,
        labels: {
            fontSize:30
            }
        }
    },

Any way to make the font bigger in the legend?

First of all, Thanks!
