Here is a custom action to do what you want. You have to copy/paste the code below into a new module (Editor Chains > Module manager > Add):

import traceback

from calibre.utils.localization import ngettext
from polyglot.builtins import iteritems
from calibre.ebooks.oeb.polish.download import (
    download_external_resources, get_external_resources, replace_resources,
)

from calibre_plugins.editor_chains.actions.base import EditorAction

class ExternalResources(EditorAction):

    name = 'Download External Resources'
    headless = True

    def run(self, chain, settings, *args, **kwargs):
        container = chain.current_container
        try:
            resources = get_external_resources(container)
        except Exception as err:
            print(err, traceback.format_exc())
            return
        if not resources:
            print(_('No external resources were found in this book.'))
            return
        try:
            downloaded = download_external_resources(container, resources)
        except Exception as err:
            print(_('Failed to download external resources.'))
            print(err, traceback.format_exc())
            return

        replacements, failures = downloaded
        if failures:
            tb = [f'{url}\n\t{err}\n' for url, err in iteritems(failures)]
            det_msg='\n'.join(tb)
            if not replacements:
                print(_(
                    'Failed to download external resources.'), det_msg)
                return
            else:
                print(_(
                    'Warning: Failed to download some external resources.'), det_msg)

        try:
            ret = replace_resources(container, resources, replacements)
        except Exception as err:
            print(_('Failed to replace external resources'))
            print(err, traceback.format_exc())
            return

    def validate(self, settings):
        return True

This is not something I am welling to work on debugging, so that is why I am not including it as part of the plugin. If you test it for some time and it is working without problems, maybe it can be added in the future.
