Azure AD SAML is a supported Identity Provider (IdP). Currently, no specific guide is available in the community for configuration on Azure side. There should be plenty of documentations available from Microsoft/other online sources for this.
As to the values you need to provide in Azure (Entity ID, Sign-on URL, etc.) - the Okta configuration guide, while it's written for a different IdP, will be a helpful reference document to provide to the team/person responsible for setting up SAML application in your Azure environment. You will then be able to download the metadata file from Azure.
Once you have the metadata file - to configure SAML in FlexNet Manager Suite Cloud, simply upload your metadata file via Web UI > System Settings > Security page. For more comprehensive guide or for on-premise guide see WebUI configuration guide OR the parent page you referred:
