I'm trying to modify a primereact theme for the dropdowns, but it doesn't seem to change a bit... Anytime that I need to modify any component brought by an external library I'm having this kind of issues when trying to adapt different things to the required style

    {lazyState.totalRecords} Results
    
        setLazyState(prev => ({ ...prev, page: 0, rows: value }))
        }
        options={[
        { label: '20 per page', value: 20 },
        { label: '30 per page', value: 30 },
        { label: '50 per page', value: 50 },
        { label: '100 per page', value: 100 },
        { label: '200 per page', value: 200 },
        ]}
    />
    
        {lazyState.page + 1} - {lazyState.totalPages}

I tried to add a height, max-height and so on rules on the css theme but changes would never appear. I also tried to apply styles on the code itself instead of the css file.
