create multiple projects error Azure DevOps rest api - powershell

Question

I am using a rest API powershell to create multiple projects in azure devops. Writing my script in below way but it fails.
Any guidance on how I can construct my script to pick up multiple names?
'
$connectionToken="token"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$ProjectUrl = "url
$Body = #{
name = #{'TestProjectCreation1','test1','test2'
}
description = 'Frabrikam travel app for Windows Phone'
capabilities = #{
versioncontrol = #{
sourceControlType = 'Git'
}
processTemplate = #{
templateTypeId = 'template id'
}
}
} | ConvertTo-Json
$projectscreated = Invoke-RestMethod -Uri $ProjectUrl -Method Post -ContentType "application/json" -Headers #{
Authorization=("Basic {0}" -f $base64AuthInfo)} -Body $Body
'

According to your description, you could create a new array for projects and foreach the project to create: scrpit like:
$url='https://dev.azure.com/{org}/_apis/projects?api-version=6.0'
$connectionToken="{PAT}"
$base64AuthInfo = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$projects= #('TestProjectCreation1','test1','test2')
Foreach($prject in $projects){
$body="
{
`"name`": `"$prject`",
`"capabilities`": {
`"versioncontrol`": {
`"sourceControlType`": `"Git`"
},
`"processTemplate`": {
`"templateTypeId`": `"6b724908-ef14-45cf-84f8-768b5384da45`"
}
}
}
"
$response= Invoke-RestMethod -Uri $url -ContentType "application/json" -Body $body -Headers #{Authorization=("Basic {0}" -f $base64AuthInfo)} -Method POST
}
