Google Ads Nodes - what API version is used?

Hi,

I am using the google Ads nodes to extract data from our google ads accounts.

Last week I got an email from google, that our account is currently using API version 18 for google ads and that version 18 will be deprecated by google very soon.

What API version are the knime nodes using in the background? I did not see any info on this within KAP (using 5.5.1).

Thank you for your help!
