How can I get Telegram message copy link using telegram API in c#

Question

I want to get the telegram message copy link using telegram API and I have read this document to understand and achieve my requirement but I didn't get the proper knowledge on this.

And I have send a message to telegram Channel using sendmessage telegram API and I get the response like below

   {"ok":true,"result":[{"update_id":498058662,  
   "message":{"message_id":18,"from":{"id":779000,"is_bot":false,"first_name":"Telegram"},"sender_chat":{"id":-1001687798866,"title":"Testing channel","type":"channel"},"chat":{"id":-1001687317586,"title":"testing group","type":"supergroup"},"date":1662100309,"forward_from_chat":{"id":-1001601708866,"title":"Testing channel","type":"channel"},"forward_from_message_id":37,"is_automatic_forward":true,"forward_date":1662100306,"text":"Ok"}}]}  

By using getupdates I'm getting this below response.

   {"ok":true,"result":[{"update_id":498858795,  
   "message":{"message_id":168,"from":{"id":779000,"is_bot":false,"first_name":"Telegram"},"sender_chat":{"id":-1001687798866,"title":"Testing channel","username":"mlZUCJ_vf_Y0ZjY9","type":"channel"},"chat":{"id":-10016245317586,"title":"testing group","type":"supergroup"},"date":1669873108,"forward_from_chat":{"id":-1004641798866,"title":"Testing channel","username":"mlZUCJ_vf_Y0ZjY9","type":"channel"},"forward_from_message_id":117,"is_automatic_forward":true,"forward_date":1669873104,"text":"Ok","has_protected_content":true}}]}
