You can create a campaign from the contacts on LinkedIn who interacted with your or another person's post using the Post feature.
To create the search, please follow the steps below:
Go to your LinkedIn account.
Click on your profile icon in the top right corner
Click on the Posts & Activity.
Click on the Posts
Click on the ellipsis icon (three dots) in the upper right corner of the post and copy the link to the post as shown below:
Now, let's import the contacts engaged in the post by pasting the post link on We-Connect.
There are 2 ways to import the contacts into We-Connect:
via Search page
Click on the "Search" menu on the sidebar menu.
Select Linkedin Posts as search type.
Paste the post link URL that you copied from LinkedIn.
Once the search populates, hit save and put a name on it. You can then go ahead and create and launch your campaign as it populates in the background.

via Campaign Setup page
Click on the "Campaigns" menu on the sidebar menu and click "Add new" campaign.
On the campaign setup page, choose Search as the lead source and select LinkedIn Posts from the search type.
Once done, you will see the form to enter LinkedIn post URL (paste the post link you have copied from LinkedIn), then enter the list name in the form below that.
The default selection of 2nd and 3rd+ connections should work as the connection type and hit continue.
