The guide for bridging your tokens to xDAI can be found here: https://docs.tokenbridge.net/eth-xdai-amb-bridge/multi-token-extension/ui-to-transfer-tokens/transfer-erc20
When you unlock the token you wish to transfer you can specify the amount of tokens to unlock or give unlimited approval. If you plan to bridge more at a later date it might be preferable to use an Infinite Unlock, to save gas in the future.
