Can I embed a mural and allow anonymous people to adapt, instead of view only?

Hi all,

I am new to mural. I am looking for a whiteboard I can embed at my website. The ideal situation would be that other people are allowed to contribute, without having to login.

In mural I can only find a view only way to embed the mural in my site.

Is it possible to embed and let other people contribute, if they are not in my team?

Kind regards,
