Is it possible to relay access_token from one web api to another in IdentityServer4

Question

Scenario : I have a client, two web apis and IdentityServer4 Token server. Client has both web apis in his scope and can call them individually. But lets say when client calls one web api and that api needs to call the other by passing access token it received. In coming token is authorized for both services. Is this possible?
