Custom Content Element Tab not showing for editor users - extbase

Question

I am dealing with a strange issue after the update to Typo3 11.5.
My extension adds several content elements to the new content element wizard in its own tab.
What does not work:
Users do not see the custom tab in the new content element wizard
What works:
Admins can see the tab in the content element wizard
Users can edit the elements once they are created
Users can change the type of an element to any of the custom elements using the "Type" dropdown
So, users seem to have all the access rights they need (confirmed in backend group settings).
The wizard seems to be configured correctly (confirmed accessing as admin).
But only admins see the tab.
If you have any hint what I could look into, I would be very grateful.
Below is the .tsconfig file I use for the wizard:
mod.wizards {
newContentElement.wizardItems {
abc.header = ABC
abc.elements {
abc_slider {
iconIdentifier = abc
title = ABC Slider
description = ABC Slider
tt_content_defValues {
CType = abc_slider
list_type = abc_slider
}
}
}
}
newContentElement.wizardItems {
abc.header = ABC
abc.elements {
abc_text {
iconIdentifier = abc
title = ABC Text
description = ABC Text
tt_content_defValues {
CType = abc_text
list_type = abc_text
}
}
}
}
}
mod.wizards.newContentElement.wizardItems.abc.show = *
I have tried adding more permissions to the backend user, but they already had rights to all elements and there was no permission setting for the tab.
I have tried adding settings to the tsconfig of the backend user and backend user group, but that did not have any effect.

As the documentation says show = * is for the plugins-tab. I had success using the documented way. So your code should look like this:
mod.wizards {
newContentElement.wizardItems {
abc.header = ABC
abc.elements {
abc_slider {
iconIdentifier = abc
title = ABC Slider
description = ABC Slider
tt_content_defValues {
CType = abc_slider
list_type = abc_slider
}
}
}
abc.show := addToList(abc_slider)
}
newContentElement.wizardItems {
abc.elements {
abc_text {
iconIdentifier = abc
title = ABC Text
description = ABC Text
tt_content_defValues {
CType = abc_text
list_type = abc_text
}
}
}
abc.show := addToList(abc_text)
}
}
