The best way is not to use this product. It’s crap. Salesforce is difficult to configure. You can do much better integrations using Pipedrive with Iguana - Salesforce is not a product for smart people who really want to control their data.
I say this from personal experience of trying to use Salesforce for a year - not only hideously expensive - it was just awful to work with. Piles of legacy crap. Very difficult development environment and I don’t like the culture of Salesforce - none of the staff seemed to know their actual product.
Honestly people need to wake up and give it the boot - it doesn’t work. Talk to anyone in an organization with Salesforce and you will find they don’t actually use for making their workflow more efficient.
At best it’s a painful part of their work to update it.
Slack is good though - you can do good things with that actually solve the problems that Salesforce doesn’t actually solve like:
Make it easy for your sales team to understand context around your customers
