Calls to an external API and problems with samesite issues with Wix cookies

Question:
I have integrated the what3words api on a site that I look after and it has been working very well. However, I have run into a problem with the _wixAB3 cookie being rejected by the api now that I am using it on a second page on the same site. It looks as though the problem is down to the _wixAB3 cookie not having the correct samesite classification and is therefore being rejected.

Can someone tell me how I can fix this through the code in velo (or elsewhere) - I haven’t been able to find any useful insights in the wix documentation.

Many thanks

What are you trying to achieve:
To access the w3w API on from dfferent pages on the same site

What have you already tried:
Internet search, Wix documentation, what3words documentation

Additional information:
I have the API key in the secrets manager and have also set up another API key in the hope that it would circumvent the issue but to no avail.
