The SDK version of the program I developed with SES is v1.5.0. Now change the development environment to vscode and import the program into vscode through "add an existing application" in the welcome interface of plug-in NRF connect. The compilation can be completed successfully. But I want to switch the SDK version to v1.7.0. I have downloaded the SDK of v1.7.0 in toolchain manager. What settings do I need on vscode to switch the SDK version to v1.7.0? thank you.
