Unable to increase Ag-grid row height

I'm using ag-grid react to add rows dynamically to the grid and have a button in one of the columns. However I'm unable to adjust the row height and as such part of the button gets chopped off like so:

I've tried setting the row height explicitly in gridOptions And tried getRowHeight callback

const [gridOptions,setGridOptions] = useState({
        rowHeight: 50,
        getRowHeight: (params) => {
            return params.data.rowHeight;
          },

None work.

What should i do?
