I am also facing the same issue and not sure which approach to follow. One of the approach that I used is as follow:

public class UnitOfWorkFilter : ActionFilterAttribute
{
    private readonly AppDbContext _dbContext;

    public UnitOfWorkFilter(AppDbContext dbContext,)
    {
        _dbContext = dbContext;
    }

    public override void OnActionExecuted(ActionExecutedContext context)
    {
        if (!context.HttpContext.Request.Method.Equals("Post", StringComparison.OrdinalIgnoreCase))
            return;
        if (context.Exception == null && context.ModelState.IsValid)
        {
            _dbContext.Database.CommitTransaction();
        }
        else
        {
            _dbContext.Database.RollbackTransaction();
        }
    }

    public override void OnActionExecuting(ActionExecutingContext context)
    {
        if (!context.HttpContext.Request.Method.Equals("Post", StringComparison.OrdinalIgnoreCase))
            return;
        _dbContext.Database.BeginTransaction();
    }
}
