Where to pass `forceAllowId` ?

I need to customize the ID generation for the User table by passing an existing user ID instead of letting the system auto-generate one. I found the documentation at https://www.better-auth.com/docs/guides/create-a-db-adapter for creating a custom adapter, but the section about user ID generation is unclear: 
additionally, it's possible to pass forceAllowId as a parameter to the create method, which allows id to be provided in the data object. We handle forceAllowId internally, so you don't need to worry about it.

My question is: Where exactly should I pass the forceAllowId parameter in the create method? I tried the following code, but forceAllowId doesn't seem to work: 
// forceAllowId is not working as expected
const newUser = await adapter.createUser({
  forceAllowId: true,
  id: userData.id,
  userId: userData.id,
  name: userData.name!,
  email: userData.email!,
  emailVerified: userData.emailVerified || false,
  image: userData.image || null,
});
// forceAllowId is not working as expected
const newUser = await adapter.createUser({
  forceAllowId: true,
  id: userData.id,
  userId: userData.id,
  name: userData.name!,
  email: userData.email!,
  emailVerified: userData.emailVerified || false,
  image: userData.image || null,
});
Could someone clarify the correct syntax for using forceAllowId to allow custom user ID creation?

Question solved: I haven't clarify the adpater and internalAdapter's diffrence. Previous code I use: 
          const adapter = ctx.context.internalAdapter;
          const adapter = ctx.context.internalAdapter;
What a stupid quesition.
