Uncaught TypeError: Cannot read properties of undefined (reading 'BlockManager')

[thatsenam]

i tried to run the code in console but it seems this library removed the default funcitonality of the grapejs library. am i wrong anyway?

window.editor.BlockManager.add('my-block-id', {
// ...
content: {
tagName: 'div',
draggable: false,
attributes: { 'some-attribute': 'some-value' },
components: [
{
tagName: 'span',
content: 'Some static content',
}, {
tagName: 'div',
// use content for static strings, components string will be parsed
// and transformed in Components
components: 'HTML at some point',
}
]
}
})
