List inside JSON Powershell - json

Question

I am trying to parse the following JSON into a PSCustomObject
[
{
"tags": [
{
"tagName": "Microsoft Teams"
},
{
"tagName": "Worldwide (Standard Multi-Tenant)"
},
{
"tagName": "General Availability"
},
{
"tagName": "Web"
},
{
"tagName": "Desktop"
}
],
"tagsContainer": {
"products": [
{
"tagName": "Microsoft Teams"
}
],
"cloudInstances": [
{
"tagName": "Worldwide (Standard Multi-Tenant)"
}
],
"releasePhase": [
{
"tagName": "General Availability"
}
],
"platforms": [
{
"tagName": "Web"
},
{
"tagName": "Desktop"
}
]
},
"id": 51230,
"title": "Microsoft Teams: New file sharing experience",
"description": "Streamline sharing with Microsoft Teams. You can now create a shareable link for any file stored in Teams and directly set the appropriate permissions. Additionally, you can also set permissions for files stored in SharePoint or OneDrive while composing a private chat or starting a channel conversation.",
"status": "Launched",
"moreInfoLink": "https://techcommunity.microsoft.com/t5/microsoft-sharepoint-blog/rich-new-file-and-sharing-experiences-throughout-microsoft-365/ba-p/960129",
"publicRoadmapStatus": "Include this month",
"created": "2019-05-08T07:00:00",
"modified": "2022-01-13T00:05:19.663",
"publicDisclosureAvailabilityDate": "March CY2021",
"publicPreviewDate": ""
}
]
I have that JSON stored in a variable like this:
$RoadmapContent = Get-Content -Raw -Path ".\M365Roadmap_single.json" | ConvertFrom-Json
And this would be my PSCustomObject:
$RoadmapItems =[PSCustomObject]#{
Title = $($RoadmapContent.title)
Tags = $($RoadmapContent.tags)
}
I would like to have this tags in a single column, like this: Microsoft Teams, Worldwide (Standard Multi-Tenant), General Availability, Web, Desktop
I have tried to accomplish that (unsuccessfully) like this:
$RoadmapContent.Tags -join ";"
How can I parse this?
Many thanks!
Edit:
I can access the tags like this:
foreach ($tag in $RoadmapContent.tags) {Write-Host $Tag.tagName}
But cannot figure out how to use this in a PSCustomObject

Figured it out thanks to a comment in the original question, here's the full code:
$RoadmapContent = Get-Content -Raw -Path ".\M365Roadmap_single.json" | ConvertFrom-Json
$RoadmapItems =[PSCustomObject]#{
Title = $($RoadmapContent.title)
Tags = $($RoadmapContent.tags.tagname -join ', ')
}
$RoadmapItems
