Hi, I would like to embed a Chatbot I made with Botpress on my Wordpress Website, but don't know how. Maybe it is very obvious, but I cannot find any help in the internet. Thanks

Did you check the documentation about publishing? Web URL will be available after publishing if you chose to create a webchatbot. Otherwise you can choose between Twitter, Insta etc

Yep, you can just cop + paste the embed code into the HTML of your webpage and the bot should load

where would one place it in the html the body?

In the head i guess but you can do it as you want

head or body works. Jsut be aware if your site uses the same header on every page, your bot will also be on every page.

How to find the body in Wordpress? Is there any possibility embedding the Bot without the Snippets Plugin?

Not sure, but there's documentation on the WP site that shows the steps https://wordpress.com/go/website-building/how-to-properly-add-javascript-to-wordpress-3-top-methods/

Some themes have a place in the admin where you can add scripts site-wide. Also on individual pages you can include an HTML block that has the botpress code just for that page.
