Hi @Isa_Thais,

Can you please ask your question in English again? That’s the official language here in this forum. Not everyone will understand Portuguese.

I advice you to have a look at the diagram-js-direct-editing module to create labels. You can then use the TextRenderer like in the following snipped or use the diagram-js Text utils and add it to the canvas yourself.
