Moving all assets and templates to another team member?

Hello,

I am leaving my current company and I am the creator/owner of all assets we have in Adobe Express with a Premium account. How do I move/give full access to another team member (who regularly uses Adobe Express to edit templates and has a premium account?

If my account is deactivated and my subscription canceled, will my colleague lose access to all the assets I have created and shared to edit with them?

I have manually shared to edit all assets with my colleague, but still unsure if they will be there once my account is deactivated.

Thanks
