How to access context.globalState inside a refresh() function of a TreeView class?

Question

I'm trying to access context.globalState.get('data'); inside a TreeView refresh() function. My refresh() looks like this:

    refresh(offset?: number): void {
        this.ctmInfrastructureCache = getGlobalStateData();
        this.parseTree();
        if (offset) {
            this._onDidChangeTreeData.fire(offset);
        } else {
            this._onDidChangeTreeData.fire(undefined);
        }

    }

The global state data is supposed to be provided by:

export function getGlobalStateData(): string {
    const data: string = context.globalState.get('ctmInfrastructureCache');
    return data;
}

However, I can't access context.globalState. I'm getting:

Property 'globalState' does not exist on type 'SuiteFunction'.ts(2339)

The new data is collected before refresh is being called and assigned to a globalState context. All I want is to get the data and provide it as input for the new TreeView.

I've tried adding context: vscode.ExtensionContext to the refresh() to no avail. How do I get access to globalState inside the refresh?

The class constructor() has access to globalState. This is working:

    constructor(context: vscode.ExtensionContext) {
        let ctmInfrastructureCacheTmp: any = context.globalState.get('ctmInfrastructureCache');
        let ctmInfrastructureCacheType: any = typeof ctmInfrastructureCacheTmp;

        // check if json needs to be converted
        if (ctmInfrastructureCacheType === "string") {
            this.ctmInfrastructureCache = ctmInfrastructureCacheTmp;
        } else {
            this.ctmInfrastructureCache = JSON.stringify(ctmInfrastructureCacheTmp);
        }
        this.parseTree();
    }

based on Mike's suggestions I've updated the code and it works now. First I've added the 'context' to the registerCommand() section of my refresh().

ctmInfrastructureProvider.refresh(undefined, context);

Then I've updated the refresh function like this, with 'context?: vscode.ExtensionContext' as an optional input.

    public refresh(offset?: number, context?: vscode.ExtensionContext): void {
        // get globalState data
        let ctmInfrastructureCacheTmp: any = context.globalState.get('ctmInfrastructureCache');
        let ctmInfrastructureCacheType: any = typeof ctmInfrastructureCacheTmp;

        // check if json needs to be converted
        if (ctmInfrastructureCacheType === "string") {
            this.ctmInfrastructureCache = ctmInfrastructureCacheTmp;
        } else {
            this.ctmInfrastructureCache = JSON.stringify(ctmInfrastructureCacheTmp);
        }

        this.parseTree();
        if (offset) {
            this._onDidChangeTreeData.fire(offset);
        } else {
            this._onDidChangeTreeData.fire(undefined);
        }

    }
