How can I add a forum on WP? free? can you help me?

Bonsoir les Amis

I am trying to add a forum on this WP website, on a Premium package, but they don’t allow me to install a plugin like BBpress unless I pay more than 200 dollars for the plugin?

Can anyone help me please?

A forum would put my followers in touch with each other and this would be more into the spirit of creating a Community around Mental Health on a challenging perspective.

I feel frustrated.

Thank you. I appreciate it.

Stay safe.
