Purchases: Update cancellation page's support link to use Odie

[jjchrisdiehl]

When a customer proceeds through the cancelation flow they have the option to 'Ask a Happiness Engineer' if they have a question:

This link leads them to our general /help page which would then require a customer to click on 'Get help' to open an omnichannel chat:

A more optimal path may be to open the omnichannel chat directly from the cancellation page, similar to a pre-sale chat during Checkout. This would allow us quick access to a churning customer for one last attempt to address any concerns.

Happy path:

@Automattic/martech Is this an oversight or is this the expected behavior of the 'Ask a Happiness Engineer' link?

Proposed Changes

• Change out the CALYPSO_CONTACT url with the Odie functionality found in Help Center.

Testing Instructions

• Go to an existing purchase under /purchases, make sure it isn't expired and can be canceled
• Click on the 'Cancel [product]' button at the bottom of the page
• Look for the Have a question? Ask a Happiness Engineer! line in the first paragraph box
• Click on the Ask a Happiness Engineer link, it should correctly open the Odie/omnichannel chat box
