adding async data to array?

const posts = await notion.databases.query({
      database_id: Deno.env.get("DATABASE_ID"),
      sorts: [
        {
          property: "Date",
          direction: "descending"
        }
      ]
    })

    const posts_array: Array<Record<string, unknown>> = [];
    
    posts.results.forEach(async post => {
      const title = post.properties.Title.title[0].text.content, date = post.properties.Date.date.start, id = post.id;
      const content = await notion.blocks.children.list({ block_id: id, page_size: 100 });
      const post_data = { title: title, date: date, content: content.results };
      posts_array.push(post_data);
    })
