**Which product are you using?**

PDF.js Express Plus 8.7.4

**Detailed description of issue**  
As I understand Express Plus doesn’t have a ‘forms’ toolbar in default header settings.  
I’m trying to add ‘forms’ to the toolbar menu in header  
using method:  
`instance.UI.setToolbarGroup(instance.UI.ToolbarGroup.FORMS)`

but it only added as an active toolbar (and I can see it in the first loading of the page and when I click on another toolbar it disappears)

Also while I’m trying to select an area for the creating new form  
it returns an error in the console

` Cannot read properties of undefined (reading 'READ_ONLY')`

**Expected behaviour**  
I want to see and use ‘forms’ in my viewer

Hello Serhii,

According to our pricing page, user form filling is available, but not creating forms.

> **[PDF.js License Pricing for Commercial Viewer | PDF.js Express](https://pdfjs.express/pricing)**

Hello Serhii,

After speaking with my team, it seems we do not support the ability to create fields such as the ones in the forms toolbar group. If you want to create forms, you will have to use something such as WebViewer: [https://showcase.apryse.com/](https://showcase.apryse.com/)

However, PDF.js Express Plus will allow user form filling as mentioned on our price page.
