What is this feature about?

代码如下，根据环境切换 disableUpload，disableUpload 禁用后走自定义上传，如何设置可以像原来那样上传会有 loading 提示

<ImageUploader
                ref={imageUploadRef}
                accept="image/jpeg,image/jpg,image/png"
                value={fileList}
                onChange={setFileList}
                upload={mockUpload}
                disableUpload={isXXX() ? true : false}
                multiple
                columns={4}
                maxCount={8}
                beforeUpload={beforeUpload}
                showUpload={fileList.length < 8}
              >
                <div
                  style={{
                    width: 80,
                    height: 80,
                    borderRadius: 8,
                    backgroundColor: '#f5f5f5',
                    display: 'flex',
                    justifyContent: 'center',
                    alignItems: 'center',
                    color: '#999999',
                  }}
                ><AddOutline onClick={handleSelectImage} style={{ fontSize: 32 }}></AddOutline></div>

              </ImageUploader>

看了一下，好像没有透出这个功能。
