Sp PageBuilder editor is not offered when a user creates an article from the joomla 4 frontend.

Hi, I installed on joomla 4.3.2 Helix 2.0 Ultimate Framework and SP PAgebuilder Pro 4.0.11.
I have enabled the "Joomla Article" integration and everything works fine when I work on joomla from the administrative side, but if I want to create an article from the frontend side of joomla, even if I act as superuser, I am not offered the switch that allows me to choose whether use the native editor or SP Page Builder, as is the case on the administrative side.
On the public side I can only create an article with the system editor and if I try to modify it it allows me but only and always with the system editor and not with SP Pagebuilder. In order to modify an article on the public side with SP Page Builder I must first intervene from the administrative side, modify it using the editor switch by choosing SP Pagebuilder and then saving, in this case I can also make changes on the public side.
Obviously this is very inconvenient and non-functional when you have several publishers.
How can I solve this crippling problem?
Thank you and good day.
