Passing multiple tags as parameters to the tag filter

[IsThisDemi]

Hello, our website gets the posts data from contentful and I have activated the tag system built in the astrowind template.
Currently I am able to show the post containing one specific tag

Is it possible to filter using multiple tag in the getstaticpath function?
This is the function:

export async function getStaticPaths({ paginate }) {
  const { items } = await contentfulClient.getEntries<PostModel>({
    content_type: 'post',
    order: '-fields.publishDate',
  });

  const posts = items.map((item) => {
    const { postSlug, title, subtitle, category, poster, content, publishDate } = item.fields;
    const { tags } = item.metadata;
    const tagIds = tags.map((tag) => tag.sys.id).map((tag) => _.startCase(_.camelCase(tag)));

    return {
      id: postSlug,
      permalink: `news/${postSlug}`,
      postSlug,
      title,
      excerpt: subtitle,
      category: category.toLocaleLowerCase(),
      image: poster.fields.file.url,
      content: marked.parse(content),
      publishDate: new Date(publishDate),
      tags: tagIds,
      readingTime: Math.ceil(getReadingTime(content).minutes),
    };
  });
  const tags = new Set();
  posts.map((post) => {
    Array.isArray(post.tags) && post.tags.map((tag) => tags.add(tag.toLowerCase()));
  });
  return Array.from(tags).flatMap((tag: string) =>
    paginate(
      posts.filter((post) => Array.isArray(post.tags) && post.tags.find((elem) => elem.toLowerCase() === tag)),
      {
        params: { tag: tag, blog: TAG_BASE || undefined },
        pageSize: APP_BLOG.postsPerPage,
        props: { tags },
      }
    )
  );
}

This is the project structure
