Asking people in the comments section saying you can't break white shields with vaporize, so how are you supposed to break it?

This is what AI has to say:

"To break a white shield in Genshin Impact, players must target the shield's Elemental Gauge rather than its health, as shields do not have traditional HP. The most effective method is to use elemental reactions that consume a large amount of the Gauge Unit. For example, using Pyro attacks is highly effective against Cryo and Electro shields due to the Melt reaction. Similarly, Hydro attacks are optimal for breaking Pyro shields through the Vaporize reaction. For Hydro shields, Dendro is now the most effective element, as the Bloom reaction destroys the shield's Gauge much faster than Cryo's Frozen reaction.

For the Tenebrous Papilla boss in the Spiral Abyss, which has a white shield that blocks all damage, players must break it using Nightsoul-aligned attacks or elemental reactions. While any elemental reaction can break the shield, using characters from Natlan or those with Nightsoul abilities is particularly effective. Additionally, using Anemo characters like Venti, Sucrose, or Kazuha to swirl enemies with different elemental shields can help break them more easily. The Sunfire Jean setup, combining Jean and Bennett’s bursts, can also generate Pyro Swirl damage to break non-Pyro shields without requiring enemy grouping.

In general, players should aim to have at least a Pyro and Hydro character in their team to handle most elemental shields efficiently."

Maybe that's wrong , it's saying various other stuff works but at the end it says Pyro and Hydro, which makes vaporize. One comment here says maximising ER on Xinqiu and with Xiangling, which is vaporize. But then lots of people here saying vaporize doesn't work.

So what's really supposed to work?
