aws-cognito-identitypool-alpha: fromIdentityPoolArn Method throws when using a string from a StringParameter lookup

[Xenoha]

Describe the bug

When using the construct to lookup an IdentityPool from a SSM StringParameter. The construct throws validation errors because it is expecting an actual string of two parts separated by a ':'.

Expected Behavior

Should be able to lookup an Identity pool with a SSM StringParameter stringValue.

Current Behavior

Code at lines 118 of the Identitypool.js file throws // if (!(idParts.length === 2)) // throw new Error('Invalid Identity Pool Id: Identity Pool Ids must follow the format <region>:<id>'); // if (idParts[0] !== pool.region) // throw new Error('Invalid Identity Pool Id: Region in Identity Pool Id must match stack region');

Reproduction Steps

const identityPool = IdentityPool.fromIdentityPoolArn(this, 'some-identityPool', indentityPoolStringParameter.stringValue)

Possible Solution

Review other constructs best practices for allowing SSM StringParameter lookup stringValue strings.

Thanks @Xenoha for reaching out . I can see in the code why this is producing an error - https://github.com/aws/aws-cdk/blob/6f21c1d91237f4caf83283492226f447b882654a/packages/%40aws-cdk/aws-cognito-identitypool-alpha/lib/identitypool.ts#L330
