How to enable Button Text Editing?

[mvierapac]

I'm using GrapesJS for the first time along with the MJML plugin. I've been adding custom blocks, and everything seems to be working fine until I realized that I can't edit the text of the buttons directly on the canvas. I've also noticed that this functionality is not available on the project's demo page either.

Is there a way to make the text of the buttons editable? I've tried different configurations with 'editable', but none seem to work. For example:
export const BTN_AQUA = { label: 'Btn aqua', category: 'basics', type: 'mj-button', editable: true, draggable: true, stylable: true, selectable: true, content: <mj-button background-color="#028484" color="white"> Botón </mj-button>, }

Also I've tried a workaround by creating a text component that looks like a button and contains an anchor with the text. However, the problem arises when editing the text; if I delete it entirely to write something else, the anchor element is lost completely, and it just write normal text.

Thanks
