Better-auth dynamic products creation

Hi! Can you help me integrate the Polar plugin with Better-Auth? Instead of defining each product statically, I would like to allow administrators to add new products dynamically from my admin panel.

Can you guide me on the correct way to implement this? I checked the documentation and found polarClient.products.list, but I’m running into type issues when trying to use it.

Here’s the default code I want to modify:

import { betterAuth } from "better-auth";
import { polar, checkout } from "@polar-sh/better-auth";
import { admin } from "better-auth/plugins";
import { nextCookies } from "better-auth/next-js";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { db } from "@/db/drizzle";
import { Polar } from "@polar-sh/sdk";

const polarClient = new Polar({
  accessToken: process.env.POLAR_ACCESS_TOKEN,
  server: "sandbox",
});

export const auth = betterAuth({
  database: drizzleAdapter(db, {
    provider: "pg",
  }),
  emailAndPassword: {
    enabled: true,
    requireEmailVerification: false,
  },
  session: {
    cookieCache: {
      enabled: true,
      maxAge: 10 * 60,
    },
  },

  plugins: [
    polar({
      client: polarClient,
      createCustomerOnSignUp: true,
      use: [
        checkout({
          products: [
            {
              productId: "(productId)",
              slug: "(productSlug)",
            },
          ],
          successUrl: process.env.POLAR_SUCCESS_URL,
          authenticatedUsersOnly: true,
        }),
      ],
    }),
    admin(),
    nextCookies(),
  ],
});
