First example button:

i = 1

feature.on('click',e=>{
  
  console.log('hello')
  
  i++
  console.log(i)
})

Get player info:

feature.on('click',e=>{
  
  console.log(e.player)
  
  console.log(e.player.wallet)
  
  console.log(e.player.name)
  
})

Update text sign:

let text_sign = parcel.getFeatureById('welcome')

  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    query: `
        query [YOUR QUERY HERE]
      `,
  }),

  .then((res) => res.json())
  .then((result) => {
    
    // do stuff here
    console.log(result)
  
  }) 

GraphQL Request Example:

  fetch('https://api.thegraph.com/subgraphs/name/poap-xyz/poap-xdai', {
