I have quick action on Work Order Object. This quick action is a type of Field Service Mobile Flow - https://help.salesforce.com/articleView?id=sf.mfs_flow_build.htm&type=5
I have added it to the correct page layout under Salesforce mobile and lightning experience actions.
When I log in as an FSL mobile user, I am unable to see that under "Actions". I made sure the page layout is correct and it has the quick action added.
I looked at this article but it does not talk about adding quick action flows - https://help.salesforce.com/articleView?id=sf.mfs_quick_actions.htm&type=5
