# Frequently Asked Questions

<details>

<summary><strong>Don't I need the Managed Package to manage and utilize GRAX?</strong></summary>

No. The Managed Package is an optional add-on that provides unique ways to use GRAX data. All GRAX features besides the Lightning Web Components can be accessed via the GRAX Application's web interface.

<summary><strong>Can I have both the First Generation and Second Generation Managed Packages installed at the same time?</strong></summary>

Technically, yes you can. We do not recommend this as it may be difficult to decipher between the different components and permission sets.

<summary><strong>Are Files (ContentDocument/ContentDocumentLink/ContentDocumentVersion) compatible with the LWC?</strong></summary>

Yes. In order to see Files within the LWC, you'll need to install the LWC on the parent object of the File you'd like displayed in the LWC (For example, to see files linked to Case records, you'll need to install the LWC on the Case object page).

<summary><strong>Why don't I see the "GRAXLWCHelper" Apex Class in the "Enabled Apex Class Access" section?</strong></summary>

Whether you're able to see the `GRAXLWCHelper` Apex Class within the `Enabled Apex Class Access` of a profile is dependent on which [users were provided access to the managed package when it was installed](https://documentation.grax.com/reuse-data/managed-packages#installing-the-first-generation-managed-package).

If you're unable to see the `GRAXLWCHelper` Apex Class within the `Enabled Apex Class Access` of a profile, we recommend updating to the [latest version of GRAX](https://documentation.grax.com/reuse-data/managed-packages#installing-the-second-generation-managed-package) and selecting the `Install for Specific Profiles` option.
