How to use acquireToken with Jetpack Compose?

How can I use acquireToken - which requires a Fragment to be passed in - with Jetpack Compose, where I don't have a Fragment?

val parameters = AcquireTokenParameters.Builder()
    .withScopes(scopes.toList())
    .withCallback(authenticationCallback)
    .withFragment(<what can I pass in here?>) // <--------- relevant line
    .build()

_msalPublicClient.acquireToken(parameters)

I am on the latest MSAL for Android, version 4.1.0
