How to get storeFrontAccess token in Shopify cli3 to use as a marketplace app?

[bovojon]

Hi all,

With Shopify CLI 2, I used the following graphql client to get a new storefront token:

const client = new Shopify.Clients.Graphql(shop, accessToken)

Then with this client, I could call the `storefrontAccessTokenCreate` mutation which worked fine.

However, since they deprecated the old version, now I need to use this client:

const client = new shopify.api.clients.Graphql({ session });

And then I am doing the same mutation with `storefrontAccessTokenCreate`. But this time, the token it returns does not work when I try to get all products. The new token I get is in a different format and when I try to get the products, it gives an error saying:

```

{"errors":"[API] Invalid API key or access token (unrecognized login or wrong password)"

```

How do we get the storefront access token with the new Shopify Cli 3 API?

Please, would appreciate some help. Been stuck on this.
