I've tried this but no luck: 

add_filter( 'rwmb_meta_boxes', 'add_pdf_metabox_product_cats', 10, 1 );
function add_pdf_metabox_product_cats($meta_boxes) {	
			$pdf_atts_procat = [];
			
			$pdf_atts_procat[] =  array(
				'name' => esc_html__( 'PDF File', 'razzi' ),
				'id'   => 'pdf_file_procat',
				'type' => 'file_advanced',
				'max_file_uploads' => 1,
				'force_delete'     => false,
				'max_status'       => false,
				'desc' => esc_html__( 'Your PDF Download File', 'razzi' ),
			);	
			$pdf_atts_procat[] =  array(
				'name' => esc_html__( 'PDF File Button Text', 'razzi' ),
				'id'   => 'pdf_file_but_text_procat',
				'type' => 'fieldset_text',
				'options' => array('butxt' => 'Button Text')
        
			);
			$meta_boxes[] = array(
			'id'       => 'pdf_download_procat',
			'title'    => esc_html__( 'PDF File', 'razzi' ),
			'taxonomies' => 'product_cat',
			'priority' => 'low',
			'fields'   => $pdf_atts_procat,
		);
		
		return $meta_boxes;	
}
