我有地图列表List<Map<String,String>>并想转换成Map<String, List String>>

下面是示例代码

List<Map<String,String>> recordListMap = new ArrayList<>();

Map<String,String> recordMap_1 = new HashMap<>();
recordMap_1.put("inputA", "ValueA_1");
recordMap_1.put("inputB", "ValueB_1");
recordListMap.add(recordMap_1);

Map<String,String> recordMap_2 = new HashMap<>();
recordMap_2.put("inputA", "ValueA_2");
recordMap_2.put("inputB", "ValueB_2");
recordListMap.add(recordMap_2);

我尝试了以下方法，但没有得到所需的结果：

Map<String, List<String>> myMaps = new HashMap<>();
for (Map<String, String> recordMap : recordListMap) {
    for (Map.Entry<String, String> map : recordMap.entrySet()) {
        myMaps.put(map.getKey(), List.of(map.getValue()));
    }
}
OutPut: {inputB=[ValueB_2], inputA=[ValueA_2]}

预期结果：

{inputB=[ValueB_1, ValueB_2], inputA=[ValueA_1, ValueA_2]}
