Add new game features to already created chunks

Please find a way to add new game features into already generated game chunks. I was disappointed when I went looking for sulfur geysers or camp sites in Bedrock v26.31. I flew out from spawn to +10,000, +10,000 and to -10,000, -10,000 and I didn't find ONE of either geyser or campsite. I'm not going to look any more. I'm just going to wait until Chunkbase has been updated so it can tell me where to go.
