OpenGL ES: What extensions allows depth textures to be filterable?

[The OpenGL ES 3.2 spec](https://www.khronos.org/registry/OpenGL/specs/es/3.2/es_spec_3.2.pdf) section seems to say that depth textures are not filterable 8.17 page 207

> Using the preceding definitions, a texture is complete unless any of the following conditions hold true:
>
> ...
> * The texture is not multisample; either the magnification filter is not
> NEAREST, or the minification filter is neither NEAREST nor NEAREST_-
> MIPMAP_NEAREST; and any of
>
> - The effective internal format specified for the texture arrays is a sized
> internal depth or depth and stencil format (see table 8.11), and the value
> of TEXTURE_COMPARE_MODE is NONE.

My understanding of that is that in OpenGL ES 3.2 depth textures are not filterable. Maybe I'm not finding it but I don't see any extension that would make them filterable. `OES_texture_float_linear` doesn't mention depth formats.
