Hilt Injection in Companion Objects

I am new to Hilt/Dagger and I have not found a good example of injecting in a companion object. Here is my singleton and data class below. I am trying to use the TargetNumber manager in the create() function. I am looking for syntax help and explaination of why.

@InstallIn(SingletonComponent::class)
@Module
data class TargetNumberManager(
val maxNumber: Int = 3, val prefix: String = "ZZ") : ITargetNumberManager {
private var currentNumber = 0

@Singleton
@Provides
override fun getNextTargetNumber(): String {
    val targetNumberBuilder: StringBuilder = java.lang.StringBuilder()

    targetNumberBuilder.append(prefix)

    val lengthOfNumber = currentNumber.toString().length

    for (i in lengthOfNumber..maxNumber step 1) {
        targetNumberBuilder.append(0)
    }

    targetNumberBuilder.append(currentNumber++)

    return targetNumberBuilder.toString()
}
}

//Data Class

data class Target(
@PrimaryKey
val targetNumber: String,
val targetType: TargetType?,
val numOfElement: Int?,
val location: Coordinate?
) : java.io.Serializable {

@AndroidEntryPoint
companion object {
    fun create(): Target {
        @Inject var targetNumberManager : TargetNumberManager
        val nextNumber = targetNumberManager.getNextTargetNumber()
        return Target(nextNumber, null, null, null)
    }
}

}
