YouTube & Telegram channels : import list of content ?!

Hi,
I am building a Glideapp which aims at listing various media issued by an economic teacher :

1/ All the video of its YouTube playlist (https://www.youtube.com/user/TKLTRADINGVIDEOS/videos).

2/ All the Voice message of its Telegram channel (https://t.me/thamikabbaj)

I have no knowledge about APIs and no idea of how to do it with my google sheet (to link it with my Glideapp).

Is anyone able to solve this challenge ?!?
Thanks !

Look into IMPORTHTML and IMPORTXML in google sheets. Sometimes you can use this to scrape info from other websites. Also look into webscrapers or some sort of zapier integration that will populate the sheet for you.
