Use these settings:

Render → Screen Space Reflections - On
Render → Screen Space Reflections → Refraction - On
Material → Surface → Principled BSDF → Transmission - 1.000

Material → Surface → Principled BSDF → Roughness - Adjust to your needs
Material → Settings → Blend Mode - Opaque
Material → Settings → Screen Space Refraction - ON
Material → Settings → Refraction Depth - Adjust to your needs, I generally suggest 0.8
but depends on the thickness of the object.
