Which file in Umbrel is same as channel.db

Does anyone know which file in umbrel has the channel data in Umbrel similar to channel.db in other Linux systems?

??? Similar in other Linux systems ???
Why would other systems have similar files to Umbrel?

I am just looking for the file that contains the latest channel data on Umbrel. The channel.db is a standard term used by developers who are involved in the lightning network, but who don’t use Umbrel for their node. I am using chantools from github. If anyone is familiar with using chantools, I would appreciate your help.

Maybe /home/umbrel/umbrel/lnd/data/chain/bitcoin/mainnet/channel.db is similar, i don’t know.

Thanks. I did find the channl.db file in /home/umbrel/umbrel/ind/data/graph/mainnet/channel.db;

Looked into /data/chain/bitcoin/mainnet/ as you said but didn’t find a channel.db there.
