Foundry VTT (tested v12) - covert all map notes to tiles, places the icon used as the tile image and links to the journal on a double click using Monk's Active Tiles

Notes to Tiles

const tileSize = 48;
const tileData= canvas.scene.notes.map(e => {
  const entryName = e.entry?.name ?? "";
  const entryUuid = e.entry?.uuid ?? "";
  return {
    width: tileSize,
    height: tileSize, 
    x: e.x - tileSize/2,
    y: e.y - tileSize/2,

    }

console.log(tileData)
await TileDocument.createDocuments(tileData, {parent: canvas.scene});

This will also add the tag "mapnote" to the tiles for added functionality, such as hiding/showing all note tiles.
