Extremely simple animation player that allows you to play an AnimationClip with a time offset. Requires an Animator component, but doesn't need an AnimationController! Check out Unity's docs cause this is basically just that: https://docs.unity3d.com/Manual/Playables-Examples.html

AnimationPlayer.cs

using UnityEngine;
using UnityEngine.Playables;
using UnityEngine.Animations;

public class AnimationPlayer : MonoBehaviour
{
	public Animator Animator;
	public AnimationClip CurrentClip => currentAnimation.IsValid() ? currentAnimation.GetAnimationClip() : null;

	public bool IsPlaying => playableGraph.IsPlaying() && currentAnimation.GetPlayState() == PlayState.Playing;

	private PlayableGraph playableGraph;
	private AnimationPlayableOutput animationOutput;
	private AnimationClipPlayable currentAnimation;

	private void OnEnable()
	{
		CreatePlayableGraph();
	}

	private void OnDisable()
	{
		playableGraph.Destroy();
	}

	private void CreatePlayableGraph()
	{
		playableGraph = PlayableGraph.Create();
		animationOutput = AnimationPlayableOutput.Create(playableGraph, "Animation", Animator);
	}

	public void Play(AnimationClip clip, float timeOffset = 0f)
	{
		if (!playableGraph.IsValid())
			CreatePlayableGraph();

		currentAnimation = AnimationClipPlayable.Create(playableGraph, clip);
		animationOutput.SetSourcePlayable(currentAnimation);
		currentAnimation.SetTime(timeOffset);
		playableGraph.Play();
	}

	public void TogglePause()
	{
		if (currentAnimation.GetPlayState() == PlayState.Playing)
			currentAnimation.Pause();
		else
			currentAnimation.Play();
	}

	public void Stop()
	{
		currentAnimation.Stop();
	}
}
