There’s an easy hack for this! Also you need to do is include the link/url to your Hubspot instance (ie copy the link to any deal or company) and paste it into the notification. Then delete the record number from that url (set of numbers before the last backslash) and replace those with the personalization token “Deal ID” or “Company ID”
Ex: HubSpot
becomes https://app.hubspot.com/contacts/2773708/deal/{DealID}
and that link will take you to the deal record!
Repeat the same for company records, ie
https://app.hubspot.com/contacts/2773708/company/3614423377/
becomes https://app.hubspot.com/contacts/2773708/company/{CompanyID}
