Hy @YiLu-MSFT
Thank you for your quick response,

according to my research, (I may be wrong) the limit is for sharepoint on-premise.
here are the lines of code in question.

before this i just get the listitems with this command: Get-PnPListItem -List $ListName -PageSize 2000 | Where {$_.FileSystemObjectType -eq "File"}

ForEach ($Item in $ListItems)
{

         $File = $Item.File
         $TotalFileSize = $Item.FieldValues.SMTotalSize 

         if($Item.FieldValues.SMTotalSize.getType() -ne [Int32])
         {
             $TotalFileSize = $Item.FieldValues.SMTotalSize.LookupId
         }
         if($TotalFileSize -gt 524288000)
         {
                
             $Versions = $Item.Versions
             $Ctx.Load($Versions)
             $Ctx.ExecuteQuery() 
             $NbVersions = $Versions.count
             $poids = $TotalFileSize
             $testnom = $item.FieldValues.FileLeafRef

thank you in advance for your help

i can embed the sharepoint website in a tab but i only have the homepage, if if click on internal link, the link open in my browser

sry for my english, I hope this comment will be more clear

thank you for reading

Thanks for reply,

as far as I can see you are not in the same conditions as me, on your screenshot, you are in a channel of a team, indeed in this case I have no worries either.
The case I mention on my side is in the context of the use of:
https://dev.teams.microsoft.com/apps for the creation of personal tabs.
I'm not sure if it's in the creation of my personal tabs or in the configuration, but I don't see where it is.

Thank you for your time.
