    BenoitLefevre As per bullet point #2, are you able to access the list from same SharePoint "tenant" or different tenant?

     

    You may need to change the value of DisableCustomAppAuthentication property at SharePoint tenant level like: 

     

    Install-Module -Name Microsoft.Online.SharePoint.PowerShell  
$adminUPN="<the full email address of a SharePoint administrator account, example: email address removed for privacy reasons>"  
$orgName="<name of your Office 365 organization, example: contosotoycompany>"  
$userCredential = Get-Credential -UserName $adminUPN -Message "Type the password."  
Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $userCredential  
set-spotenant -DisableCustomAppAuthentication $false
