Any good online resources to learn Tulu? (Probably a stupid question)

A bit of background: I'm from a Catholic family who moved from Udupi to Mumbai when I was a 3 year old. We speak Konkani as our mother tongue at home and I'd consider myself pretty fluent in the language. However, if my parents wanted to share a secret with each other which they didn't want me to understand, they'd speak Tulu with each other to do the needful. I kinda picked up on a few Tulu words and their meanings and I can understand simple contexts around conversations. But it would be nice to learn the language on a deeper level (probably the spoken part of it) I work and stay in Bangalore now and I can reveal (at the risk of angering Kannada activists if they exist in this sub) that I do not know to speak a word of Kannada and I can't read it too (Can understand a bit of contextual conversations, but that's all) Considering this background can someone point me towards online resources for e.g. a Duolingo type platform to learn Tulu? Will be much appreciated! Thanks.
