How to activate the Make an Offer Inline Form app block
If the Enable inline setting is turned on for an offer, the Make an Offer app will automatically place the inline form near the Add to Cart button on your product page. You can also choose exactly where the inline form appears by adding an app block to your theme.
In your Shopify admin, go to Online Store > Themes.
Find the theme you want to edit and click Customize.
Open the drop-down menu at the top of the page.
Select Products, then select the product template you want to edit.
In the side panel, click + Add block or + Add section, depending on where you want the Make an Offer inline form to appear.
Under the Apps section, click Make an Offer Inline Form to add the block.
Click Save to activate it.
