how to convert like %searchKey% to native query in spring boot jpa

问题

I'm trying to convert the following query to native query, I'm getting empty list while the query is returning 2 tuples

following is the query :

SELECT 
  s.id AS shopID,
  s.shop_name AS shopName 
FROM
  shop s 
WHERE s.shop_name LIKE '%store%' ;

following is the method I've created which is returning empty list while it's supposed to send a list containing two objects (this is the method of m repository)

    @Query(value = "SELECT \n" +
            "  s.id AS shopID,\n" +
            "  s.shop_name AS shopName \n" +
            "FROM\n" +
            "  shop s \n" +
            "WHERE s.shop_name LIKE %:searchKey%", nativeQuery = true)
    List<Object[]> buyerDashboardSearchSuggestion(@Param("searchKey") String searchKey);

result of query

following is my postman request

{
    "searchKey": "store"
}

I doubt the combination of %:searchKey% in a native query, I think % must be part of the parameter.

@Query(value = "SELECT \n" +
            "  s.id AS shopID,\n" +
            "  s.shop_name AS shopName \n" +
            "FROM\n" +
            "  shop s \n" +
            "WHERE s.shop_name LIKE :searchKey", nativeQuery = true)
List<Object[]> buyerDashboardSearchSuggestion_internal(@Param("searchKey") String searchKey);

default List<Object[]> buyerDashboardSearchSuggestion(String searchKey) {
    return buyerDashboardSearchSuggestion_internal("%"+searchKey+"%");
    //todo escape special chars like % and _ in "searchKey"
}
