URP (Unlit Graph) alpha does not work in the particle system

Hello everyone, alpha does not work in the particle system in unity. I used the tutorial guide from @GabrielAguiar in the HDRP render everything works fine , I decided to do the same in the URP render and the alpha channel does not want to work, tell me what is wrong ?
The goal is to manage transparency in the particle system and color over lifetime

On additive blending your alpha is your color basically. Particle will fade when you set darker color.
You should change blend to Alpha.

Thank you so much , it helped, I’m glad that I can continue to do what I planned =)

Blend:Alpha will give you a different visual result than Blend:Additive, it is also more expensive.
If you want to continue using Additive but have Alpha support you can multiply RGB * A and then plug the result into the output colour.
