I don't see the business model or rationale for a CMS (WP) - CRM amalgamation when you can get free and terrific standalone CRM called EspoCRM (https://www.espocrm.com/) which installs with about the same non-complexity as WP and is far better than the NoBS plugin.

Sometimes, just because it CAN be done does not mean it SHOULD be done.

YMMV.
