Execute multiple commands with && in systemd service ExecStart on RedHat 7.9

I have this systemd service on Red Hat Enterprise Linux Server 7.9 (Maipo)

[Unit]
Description = EUM Server Service
PartOf=eum.service
# Start this unit after the app.service start
After=eum.service
After=eum-db.service

[Service]
Type=forking
User=root
WorkingDirectory=/prod/appdynamics/EUMServer/eum-processor/
ExecStart=/usr/bin/sleep 45 && /bin/bash bin/eum.sh start
RemainAfterExit=true
ExecStop=/bin/bash bin/eum.sh stop

[Install]
WantedBy=multi-user.target

that fails because it tries to pick everything after /usr/bin/sleep as parameters to that command. I just want to execute the /usr/bin/sleep 45 and on success execute bin/eum.sh start. How can I make it work?

The command line is not given to a shell, so && is not valid. You would need, for example,

ExecStart=/bin/bash -c 'sleep 45 && /bin/bash bin/eum.sh start'

or you could separate the commands into

ExecStartPre=/usr/bin/sleep 45
ExecStart=/bin/bash bin/eum.sh start
