How to add the multiple image uploading feature in Wagtail?

I am primarily working with Django, Wagtail, and API serializers, without using templates directly for HTML rendering. Instead of HTML templates, I use Django’s and Wagtail’s API features to render content.

Currently, I’m looking to add a new feature: multiple image uploading on the backend. Right now, with Wagtail, I can only upload a single image at a time. However, we need to modify this feature so that multiple images can be uploaded at the same time…

Let me clear my point my uploading a image. where the wagtail/images/muliple/add where user can add multiple images , but in default case we can only add one image at a time .What I need is for the ability to upload multiple images to be implemented in the default structure.

my code structure is like this:

======================================

blocks.py:

from wagtail.images.blocks import ImageChooserBlock
from wagtail.models import Site, Page
from cms.core.models import get_rootless_url_path
import re
from wagtail.images.models import Image
from wagtail.templatetags.wagtailcore_tags import richtext


class ImageChooserRenditionsAPIBlock(ImageChooserBlock):
    def get_api_representation(self, value, context=None) -> dict:
        from .serializers import ImageSerializer

        return ImageSerializer(value).data


class GreeterBlock(StructBlock):
    label = TextBlock()
    # description = TextBlock()
    description =CustomRichTextBlock(features=['h1', 'h2', 'h3', 'h4', 'h5', 'bold', 'italic', 'ol', 'ul', 'hr', 'link', 'image', 'code', 'blockquote'] )  
    image = ImageChooserRenditionsAPIBlock(required=False)
    video = CustomDocumentChooserBl`ock(required=False)
    cards = StreamBlock(
        local_blocks=(("cards", CardBlock()),),
        required=False,
    )


serializer.py:

class ImageSerializer(serializers.ModelSerializer):
class Meta:
model = get_image_model()
# fields = (“id”, “title”, “width”, “height”, “renditions”)
fields = (“id”, “title”, “width”, “height”, “file”)


urls.py:

from django.urls import path, include
from wagtail import urls as wagtail_urls
from wagtail.admin import urls as wagtailadmin_urls
from wagtail.documents import urls as wagtaildocs_urls
from wagtail.api.v2.router import WagtailAPIRouter
from wagtail.documents.api.v2.views import DocumentsAPIViewSet
from wagtail.images.api.v2.views import ImagesAPIViewSet
from cms.meta import urls as meta_urls
from .views import CustomPagesAPIViewSet

api_router = WagtailAPIRouter("wagtailapi")
api_router.register_endpoint("pages", CustomPagesAPIViewSet)
api_router.register_endpoint("images", ImagesAPIViewSet)
api_router.register_endpoint("documents", DocumentsAPIViewSet)


urlpatterns = [
    path("", include(wagtailadmin_urls)),
    path("content/documents/", include(wagtaildocs_urls)),
    
]

api_urlpatterns = [
    path("", api_router.urls),
    path("meta/", include(meta_urls.urlpatterns)),
]

I am not that familiar with Wagtail. Could anyone please help meyour text

I need an answer that can help me solve the issue of multiple image uploads using the default Wagtail image field.
