⚠️ Constraint: On newer Sharepoint (after 2019) Grant App permission as it is disabled by default. To enable Custom Application APP Authentication run the following PowerShell commands:

Install-Module -Name Microsoft.Online.SharePoint.PowerShell
$adminUPN="<SharePoint administrator account>"
$orgName="<name of your Office 365 organization>"
$userCredential = Get-Credential -UserName $adminUPN -Message "Type the password."
Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $userCredential
get-spotenant | Select DisableCustomAppAuthentication
set-spotenant -DisableCustomAppAuthentication $false

Or

$creds = Get-Credential
$orgName="<name of your Office 365 organization>"
Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $creds
get-spotenant | Select DisableCustomAppAuthentication
set-spotenant -DisableCustomAppAuthentication $false

Advantage(Compared with MSGraph API Delegated Permission): Stream upload supported. There is no temporarily stored local file during the upload.
