How to insert <TAB> after word?

[funny-falcon]

Our coding standard require to insert after type name on variable/field declaration:

struct A {
  size_t/*TAB here*/fsize;
  size_t/*and I try to type it here*/
};

When I type size_t autocompletion window pops up, and starts choose of variants, and I don't get how to insert just itself.

Can you help me?

Do C-c to close the popup and then try to insert with S-tab. (By default, pressing tab when not at the whitespace beginning of a line will use smart-tab behavior where the cursor will jump to the end of the current syntax node. But this can be overridden as shown in https://docs.helix-editor.com/editor.html#editorsmart-tab-section)
