journalctl doesn't show logs of a snap

When I run a snap application in the terminal like this:

/usr/bin/snap run shadowsocks-rust.ssserver -c /etc/shadowsocks-rust/config.json

I see the logs:

2023-05-14T18:55:11.714373725+03:00 INFO  shadowsocks server 1.15.3 build 2023-03-12T16:38:32.068195882+00:00
2023-05-14T18:55:11.715955767+03:00 INFO  shadowsocks tcp server listening on 0.0.0.0:12345, inbound address 0.0.0.0:12345

But when I run the same as a systemd service:

[Unit]
Description=shadowsocks service
After=network-online.target

[Service]
User=myuser
ExecStart=/usr/bin/snap run shadowsocks-rust.ssserver -c /etc/shadowsocks-rust/config.json
Restart=always

[Install]
WantedBy=multi-user.target

The only logs I see are from systemd (journalctl -u shadowsocks.service):

May 14 18:37:08 mypc systemd[1]: Started shadowsocks service.

Service status:

# systemctl status shadowsocks.service

How can I make journalctl show logs of a snap running as a systemd service?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
