“List all companies API” is not returning any data

Hi,
I am using “unstable” version of intercom API to build KickFire app. I have created a company using “Create company API” . I have attached two contacts with that company using “Attach contact API” . One of the contact has “role : user” and another contact has “role: lead” . However, I cannot fetch any company using “List all companies API” ( no company data returns ) . I can see my created company using “Retrieve a company API”. “List attached contacts” also returns two contact information.

Can you please help me understand why “List all companies API” is not returning any data even though it has been attached with two contacts ?

Thanks
Layla
