I think the problem is the jurisdiction.

Many of Telegram payment-related services use https://smart-glocal.com/, which is registered in Hong Kong (with a UK company handling EEA operations). They don’t say it on the website, but I believe they do work with Ukrainian (and apparently even Russian) citizens and can handle payouts there. (Note, however, that Smart Glocal is owned by a pro-Kremlin guy from Russia: https://en.zona.media/article/2022/08/08/premiumdonate-trl)
