"Everyone" Dynamic Group not appearing for share in Sharepoint Online

Question

I am using Sharepoint Online (Office365). There are some default dynamic groups - "Everyone" and "Everyone except External Users", however I can only see "Everyone except External Users" when setting a permissions to some object. My goal is to share a site (kind of a landing page) where all external users would have access while the subsites have different groups and external users.

Answer 1

Found a solution, that worked.

Set-SPOTenant -ShowEveryoneClaim $true

Now "Everyone" appeared in the search and works as expected.
