How to add Docusign App to all the subsites using powershell or selenium?

Question

Currently I am running into an issue. I have an app installed from the SharePoint store "Docusign" and it is at the top level site collection. I have to manually go to every subsite and click the gear and choose add an app, then choose docusign and then click Trust It. I want to enable this "app" on all the subsites of said site collection with a Powershell script/command.

Site Collection 1 Where app was initially added

Subsite1 Subsite2 ....etc I am very new to powershell and I have tried to copy and paste some scripts together to get this to work but keep hitting a wall. Any help on this would be greatly appreciated or should I approach this a different way?

$app = new-object -com shell.application $ie=$app.windows() $ie=$ie | ?{$_.locationurl -match "SiteCollectionURL"}

if($ie -ne $null) { Write-host Connected $url='https://test.sharepoint.com/sites/Site/subsite5/_layouts/15/storefront.aspx?source=%2Fsites%2FSite%2Fsubsite5&sname=subsite5#qry=%22Docusign%20for%20SharePoint%22,vw=AppDetailsView,app=WA104218069,clg=0' $ie.Navigate($url) Start-Sleep -s 10

$addItButton=$ie.Document.body.getElementsByTagName('button') |? {$_.value -match 'Add' }
if($addItButton.disabled -eq $false)
{
    $addItButton.click()
    Start-Sleep -Seconds 5
    
    $trustIt=$ie.Document.IHTMLDocument3_getElementById('ctl00_PlaceHolderMain_BtnAllow')
    
    $trustIt.click()
}

//The above code successfully clicks on Add button but when the pop up comes, the above code fails to click on Trust It button

For managing apps tenant level, you will need to first create a SharePoint app catalog. Then you can manage the app deployment there. Here are tutorials about it, have a check on it. And just like you said, after the deployment, still you will need to add the app by hand(Trust it and add it). After deployment in app catalog, it makes the app available on those sites.
