How to use the node-coap-client.CoapClient.tryToConnect function in node-coap-client

private async tryToConnect(identity: string, psk: string): Promise {

		// initialize CoAP client
		coap.reset();
		coap.setSecurityParams(this.hostname, {
			psk: { [identity]: psk },
		});

		log(`Attempting connection. Identity = ${identity}, psk = ${psk}`, "debug");
		const result = await coap.tryToConnect(this.requestBase);
		log(`Connection ${result ? "" : "un"}successful`, "debug");
		return result;
	}
