Translate block labels for grapesjs-preset-webpage

How tot translate labels for:

https://github.com/artf/grapesjs-preset-webpage/blob/master/src/blocks/index.js

for basicOpts I'm doing fine with:

                   pluginsOpts: {
			        'gjs-preset-webpage': {
			             // options
			        	blocksBasicOpts: {
			        		// label 
			        	 	labelColumn1: "1 Colonna",
			        		labelColumn2: "2 Colonne",
			        		labelColumn3: "3 Colonne",
			        		labelColumn37: "2 Colonne 3/7",
			        		labelText:"Testo",
						labelLink:"Link",	
						labelImage:"Immagine",	
						labelVideo:"Video",	
						labelMap: "Mappa",
							 

thanks!
