[teranailee]

I try to change tooltip for "+" button and it not working.

<FormBuilder

                            schema={jsonSchema || ''}
                            uischema={jsonUiSchema || ''}
                            onChange={(newSchema: string, newUiSchema: string) => onBuilderChange(newSchema, newUiSchema)}
                        
                            mods={{
                                tooltipDescriptions:{
                                    add: 'Add More Connector',
                                },
