Cannot to publish the plugin as forced to use "documentAccess": "dynamic-page", in the manifest

Trying to publish the plugin but forces to use "documentAccess": "dynamic-page", in the manifest.
This has in turn requests that async versions of funtions are used which I have trouble with.

For example I cannot do

let collections = figma.variables
    .getLocalVariableCollections()
    .reduce((into, collection) => {
      into[collection.name] = {
        name: collection.name,
        id: collection.id,
        defaultModeId: collection.defaultModeId,
        modes: collection.modes,
      };
      return into;
    }, {});`

anymore as it wants getLocalVariableCollectionsAsynch() to be used instead.

Tried using it as

 const sleep = (n) => new Promise((res) => setTimeout(res, n));
 let collectionsAsync = await figma.variables.getLocalVariableCollectionsAsync();
            let arr = await collectionsAsync
            .reduce( async (into, collection) => {
            await sleep(10);
              into[collection.name] = {
                name: collection.name,
                id: collection.id,
                defaultModeId: collection.defaultModeId,
                modes: collection.modes,
              };
              return (await into);
            }, {});

but couldn't make it work.
Any thoughts?
