Is there a telegram bot that can notify when there are 3 messages in a row with the same keyword in someone else's channel?

Question

Bots

We need a bot that could notify me when there would be 2 or 3 posts in a row in someone else's channel with a keyword, let's say "#x" .
Example:
1st post "Blah blah blah #x"
2nd post "Blah blah blah #x"
And I get a notification from this bot
I hope you understand
