• [nitpick] The explicit import of companion object members can be removed, since Kotlin allows direct access to EXTRA_ERROR_MESSAGE and EXTRA_THROWABLE without importing them.

import at.bitfire.icsdroid.ui.views.CalendarListActivity.Companion.EXTRA_ERROR_MESSAGE

• [nitpick] Consider using continuation.invokeOnCancellation { call.cancel() } before enqueueing. This separates cancellation handling from the resume logic and avoids the less-readable multi-parameter lambda on resume.

continuation.resume(value = response, onCancellation = { _, _, _ -> call.cancel() })
