Can't ban channel from reactions

Steps to reproduce

Someone uses a channel to spam our group by adding negative reactions to a lot of messages in our group. We can't ban it since it has never sent any messages.

Expected behaviour

A way to ban channels that only adds reactions from a group.

Actual behaviour

No way to do this in Telegram desktop (but I can do it via the API since the channel is public).

Operating system

Arch Linux

Version of Telegram Desktop

4.15.2

Installation source

Static binary from official website
