How to customize styles of the Search Text Field

[hire2gis]

Hi. There's an article on docs site how to customize Search Text Field https://www.material-react-table.com/docs/guides/global-filtering#customize-the-search-text-field
I'm trying this code:
muiSearchTextFieldProps: { placeholder: 'Search all users', sx: { minWidth: '300px', color: white }, variant: 'outlined', },

But it didn't working: minWidth and color didn't applying to search input.
Is it bugged or I'm doing something wrong?
