From private chat group to private channel

[rudolf-weissenegger]

Hey,
I would like to change a private chat group to a private channel, but this is not possible directly on Telegram.

So I thought to export the complete chat and import it in the newly created channel, but the TLMerger only shows me the two channels/groups with the newest posts.

Am I doing something wrong or is there a problem in TLMerger?
Or do you know some other way to do what I would like to?

Telethon probably needs updates as Telegram has rolled multiple layer updates since the last update of this tool.

I no longer maintain these tools, but I'll happily accept pull requests that updates TLMerger to the newest layer version ensuring all functionality is kept intact.

Thanks for your reply, but I have no clue how to do that.

Is there someone out there which could help, please?
