As you know that GeyserMC does not link both of your Java / Bedrock accounts unless you join their account linking server. This can be done if you have an Online account. However, if you are using a cracked account, this is certainly not possible. You can join the server from a Bedrock Edition client but not from the Java Edition client.
Now this is a problem, you cannot link your accounts unless you have offline linking enabled. Now enabling this is possible however you cannot upload the required files because
Here is the documentation.
Dear Aternos, please allow us to upload those files as requested by GeyserMC. Or for people with not much experience, please add a button like Enable Geyser Linking. (Requires GeyserMC installed)
