Unfortunately Linkedin no longer make the feed available to embed like the other social media apps. The options for embedding are limited and listed on their public site here https://docs.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/plugins?context=linkedin/consumer/context
- Share - allows to share content with LinkedIn network (doesn't apply to you since your pages are not public)
- Follow- allows a user to follow a particular company (i.e. you could make it easier to your employees to follow 3 Day Blinds Corp profile on LinkedIn)
- Autofill - allows to leverage LinkedIn profile info to fill profile fields on a form
There is an option for you to use a 3rd party vendor for a Linkedin feed.
Let us know if you have any questions.
