SharePoint Wiki Pages Migration (Downloading instead of Opening)

Question

Hello everyone,
I am trying to migrate SP2016 Wiki pages to SP Online by moving the pages to Site Assets and then using SPMT to migrate Site Assets to SPO. But after the migration is done when I click on any .aspx page in Site Assets it will be downloaded instead of opening in the browser. I tried also to move the pages to the wiki pages library using PNP and still, the pages are downloaded when I click on any of them. Any idea why the Url got changed to include a download option instead of web=1?
@JulieWang-MSFT sharepoint-wiki-pages-migration.html your solution worked here but stuck with the download option.

You could follow below steps to open migrated ASPX files.

1.Enable custom script by using PowerShell.

#Config Parameters  
$AdminSiteURL="https://tenant-admin.sharepoint.com"  
$SiteURL="https://tenant.sharepoint.com"  

#Get Credentials to connect  
$Cred = Get-Credential  

#Connect to SharePoint Online Tenant Admin  
Connect-SPOService -URL $AdminSiteURL -Credential $Cred  

#sharepoint online enable custom scripts powershell - Disable DenyAddAndCustomizePages Flag  
Set-SPOSite $SiteURL -DenyAddAndCustomizePages $False  

2.Download all ASPX files, delete all ASPX files in the document library, upload them into document library again by using upload button. Then you could open migrated ASPX files.
