How do I get my mutation to return a value?

Im trying to get my mutation to return the object after its been created. My router code is

  createAnswerCollection: publicProcedure
    .input(
      z.object({
        userId: z.string(),
      })
    )
    .mutation(async ({ ctx, input }) => {
      const answerCollectionObject = await ctx.prisma.answerCollection.create({
        data: {
          userId: input?.userId,
        },
      });
      return answerCollectionObject;
    }),

  createAnswerCollection: publicProcedure
    .input(
      z.object({
        userId: z.string(),
      })
    )
    .mutation(async ({ ctx, input }) => {
      const answerCollectionObject = await ctx.prisma.answerCollection.create({
        data: {
          userId: input?.userId,
        },
      });
      return answerCollectionObject;
    }),

And my front end code is

      const getAnswerCollection = answerCollectionMutation.mutate({ userId });
      console.log(`getAnswerCollection`, getAnswerCollection)

      const getAnswerCollection = answerCollectionMutation.mutate({ userId });
      console.log(`getAnswerCollection`, getAnswerCollection)

the console log keeps returning undefined. How do I get it to return the object? when I look at getAnswerCollection it says void
