How to use Generics on this class?

Question

How would one go about implementing generics on MySerializer below?

The SomeGenericClass type is what I would like to make generic.

I understand that this is an object which cannot be generified by definition. How can it be translated into a class to allow generification?

import androidx.datastore.core.Serializer
import kotlinx.serialization.json.Json


object MySerializer: Serializer<SomeGenericClass> {
    override val defaultValue: SomeGenericClass
        get() = SomeGenericClass()

    override suspend fun readFrom(input: InputStream): SomeGenericClass {
        return try {
            Json.decodeFromString(
                deserializer = SomeGenericClass.serializer(),
                string = input.readBytes().decodeToString()
            )
        } catch (e: SerializationException) {
            e.printStackTrace()
            defaultValue
        }
    }

    override suspend fun writeTo(t: SomeGenericClass, output: OutputStream) {
        output.write(
            Json.encodeToString(
                serializer = SomeGenericClass.serializer(),
                value = t
            ).encodeToByteArray()
        )
    }
}
