Mandatory Fields in Angular Web Portal for new identity creation

I thought the option 'Property editors / Primary editable properties' would turn the added properties into mandatory ones
when creating an object but it doesn't (v93)

Administration Portal > Configuration: Web Portal (click on: three dots icon)

Create configuration key
Property editors / Primary editable properties
Person
[Create]

Feature configuration (QER)
Property editors / Primary editable properties / Identities
These are the main properties required for creating an object. (does this mean mandatory?)

[Add New]
Company (UID_FirmPartner)

And then for the onloaded persons my thought was to put this in the Table scripts: Script (Onloaded) of the person table.

If AppData.Instance.AppType = AppType.Web AndAlso _
        AppData.Instance.AppName.Equals("QBM") Then

    Entity.Columns("UID_FirmPartner").MinLen = 1
End If

is it defect in Product.

Just double-checked it, had some more time to test it out.

1: The option "Property editors / Primary editable properties" only show's the properties needed when creating a new object but doesn't make them mandatory. (so no defect my misunderstanding of the feature)

2: The .MinLen = 1 works so you can make properties mandatory for onloaded objects exclusively for the Portal: changed the script in above post should work now. (also no defect my coding mistake)

3. To make the property only mandatory in the portal when creating a new object I think your only option is to modify the HTML application.
Something like this:
imxweb\projects\qer\src\lib\identities\create-new-identity\create-new-identity.component.ts 
so after the line: this.cdrListPersonal = ... or this.cdrListOrganizational = ...
depending in which list where your added property is placed

this.cdrListPersonal.map((field) => {
if(field.column.ColumnName === "The column name goes in here") {
field.minLength = 1;
}
})

4: Or put this in the Table scripts: Script (Onsaving)  as a temp. workaround

If AppData.Instance.AppType = AppType.Web AndAlso _
        AppData.Instance.AppName.Equals("QBM") AndAlso _
        String.IsNullOrEmpty($UID_Locality$) Then

    Throw New ViException(#LD("You are required to add a company, and we need an angular developer to make this prettier")#, ExceptionRelevance.EndUser)
End If

Thanks Niels for your help, 

option 4 we already have in place.

I will try to update HTML code.
