Q: Can I export type in documentationjs and link it in a reference type in @param? What I want to do looks like this:
/**
* @class OrganizationDescriptor
*/
export type OrganizationDescriptor = {|
  organizationId: string
|};

and then when I use this type as a parameter, document it:
/**
* @param {OrganizationDescriptor} descriptor.organizationId returns {@link OrganizationDescriptor}
*/

I tried assigning a function that returns an object with an organizationId string type. It does work, but it will require a lot of time editing my current codebase.
Is there a way to export type and use it as type reference of a parameter?
I run documentation v12.1.4 and run it using Node.js

A: Well, the answer is pretty easy. All I had to do is also transpile the types file and add some text to a type.
something like this,
/**
  * OrganizationDescriptor description
*/
export type OrganizationDescriptor = {|
  organizationId: string
|};

and use it as
 /**
   * @param {object} descriptor
   * @param {OrganizationDescriptor} descriptor.organizationId 
 */
 info(descriptor: ActivityDescriptor) {

worked for me.
You should also not forget that there is @type namepath available. Might be useful.
