How to track more than 100 pairs?

[EUA]

I have this error when I try to track more than 100 pairs.

{'id': 'xxxx', 'type': 'error', 'code': 509, 'data': 'exceed max subscription count limitation of 100 per time'}

Can't find how to do.

Topic Subscription Limit
Maximum number of batch subscriptions at a time: 100 topics
Subscription limit for each connection: 300 topics

If you really need to subscribe to so many topics, you can use multiple sub-accounts to subscribe

How can I increase it to 300 on one connection?
What is the way to do it?
Do I need to pause for some seconds after subscribing 100 pairs?
